The present invention makes it possible to rapidly deposit perovskite crystals while suppressing a decline in smoothness of a perovskite crystalline film. A perovskite crystal deposition apparatus comprises: a base body stage on which a base body is to be placed; a blade which is disposed so as to face the surface of the base body such that a gap is formed therebetween when the base body is placed on the base body stage; and a gas supply member that sprays a gas at a pressure of 0.3-0.6 MPa, a temperature of 25-200 C., and a flow rate of 30-40 L/min onto the surface of the base body With the deposition apparatus, a perovskite crystalline layer is obtained by spraying a gas from the gas supply member onto a precursor film that has been obtained by spreading a precursor solution of perovskite crystals on the base body using the blade.

A production apparatus of an electrode mixture layer, comprising: a support unit; a feeding unit that feeds granulated particles on or above the support unit; a conveying unit that conveys the granulated particles that have been fed on or above the support unit; a squeegee unit that levels the conveyed granulated particles to form a granulated particle layer, the squeegee unit including a passage portion, and non-passage portions that are provided at both ends of the passage portion; and a forming unit that applies a load to the granulated particle layer to form an electrode mixture layer, wherein the squeegee unit has a first adjusting mechanism capable of continuously changing a gap in a width direction so that gaps at end portions in the width direction of the passage portion are narrower than a gap at a central portion.

Provided is a manufacturing method for an optical fiber tape core wire (10) including: coating a plurality of optical fibers (20) with a resin in an uncured state; removing, by a removal part (120), the resin in the uncured state partially; and curing the remaining resin in the uncured state. The removal part (120) includes a rotary blade (121), a slit (126), positioning part (122), and a suction part (123). In the removing of the resin, the resin in the uncured state between the optical fibers (20) is extruded to the outlet opening (126a) while moving the optical fibers (20) from upstream to downstream, and the resin in the uncured state extruded through the outlet opening (126a) is suctioned by the suction part (123).
