A method of manufacturing an electronic component that includes preparing unfired multilayer bodies each including main surfaces opposite to each other in a stacking direction, side surfaces opposite to each other in a width direction, and end surfaces opposite to each other in a length direction. One of the side surfaces of each of the unfired multilayer bodies is bonded to an adhesive sheet, and the other side surface of each of the unfired multilayer bodies is polished by rotating a polishing surface of a rotary polishing machine while contacting the other side surface. An insulating layer is formed on the polished other side surface. In the polishing of the other side surface, at least one of the rotary polishing machine and the adhesive sheet is moved relative to the other thereof to form a polish groove in the length direction.

A manufacturing method of an electronic device is provided. The manufacturing method of the electronic device includes following steps: providing a substrate; bonding at least one electronic component to the substrate, wherein the at least one electronic component is mainly driven by a reverse bias in an operating mode; applying a forward bias to the at least one electronic component, and determining whether the at least one electronic component is normal or failed; and transporting the substrate configured with the at least one electronic component determined to be normal to a next production site or repairing the at least one electronic component determined to be failed.

A power storage device and an applicator is obtained that achieve an increase in capacity and an improvement in productivity, and that enable the thickness of a mixture layer to be inhibited from varying. A positive electrode mixture slurry is discharged into discharge regions of a belt-like positive electrode current collector that extend in a length direction of the positive electrode current collector from discharge nozzles corresponding to the respective discharge regions to form a positive electrode mixture layer on the positive electrode current collector. The discharge regions are arranged such that a part of each of the discharge regions overlaps a part of another of the discharge regions adjacent thereto when viewed in the length direction to form overlapping portions. The positive electrode mixture slurry is intermittently discharged to form an exposed portion on at least one of the discharge regions.

Systems and methods of additively manufacturing passive electronic components are provided. An additive manufacturing device may deposit a material to create a passive electronic component. A sensor may continuously measure an electrical property of the passive electronic component across two electrical contacts as the material is deposited during manufacturing. The sensor may transmit the measured electrical property to a processor whereby the processor may adjust a material deposition rate of the additive manufacturing device. The continuous measurement of the electrical property and adjustment of the material deposition rate as the passive electronic component is produced allows for passive electronic components to be manufactured to a high degree of accuracy of the electrical property.

A lead wire straightening device including a control device that disposes a lead wire of a lead component that is held by a holding section between a first claw section and a second claw section. The control device causes an opening/closing driving section of a straightening unit to clamp and straighten the lead wire by the first and second claw sections. After the lead wire is clamped, the control device causes a driving section to rotate at least one of the holding section and the straightening unit to thereby change positions of the first and second claw sections relative to the lead wire. Then, after changing the positions of the first and second claw sections relative to the lead wire, the control device causes the first and second claw sections to clamp the lead wire again to straighten the lead wire.

An impurity processing device includes: a pipe through which a treated liquid containing metal impurities flows; a first electrode and a second electrode disposed in the pipe; and a power supply causing a current to flow between the first electrode and the second electrode.

An impurity processing device is a device for processing metal impurities contained in a solid-liquid mixture for forming an electrode of an electric storage device, and includes a first electrode and a second electrode that apply an electric field to the solid-liquid mixture, and a power supply that causes a current of 0.1 mA or more to flow between the first electrode and the second electrode.
