A glass wiring board that can be kept from cracking by better preventing concentration of stresses in a glass plate on which a conductor layer including an electrolytic copper plating layer is provided, the wiring board includes: a glass plate; a first metal layer covering at least a part of the glass plate; and a second metal layer covering at least a part of the first metal layer, and the area of the first metal layer in contact with the second metal layer is smaller than the area of the second metal layer facing the first metal layer.

According to one embodiment, a wet-area device includes a main part, a first layer, and a second layer. The first layer is provided on an outer surface of the main part. The second layer is provided on an outer surface of the first layer. A hardness of the second layer is greater than a hardness of the first layer. The first layer includes a first unevenness at a side of the outer surface of the first layer. The first unevenness includes a plurality of recesses and a plurality of protrusions. The second layer includes a second unevenness at a side of an outer surface of the second layer. The second unevenness includes a plurality of recesses and a plurality of protrusions. The second unevenness is arranged along the first unevenness. An average height of the first unevenness is less than an average length of the first unevenness.

The present disclosure relates to a metal air filter including: a filter which is formed of a metallic material by electrodeposition and has a nano branch structure; an ionizer which conducts particles to be captured by the filter with negative charges; and a power supply which supplies a positive voltage for conducting the filter with positive charges and a negative voltage for the ionizer. The filter can be more simply manufactured at a lower cost than a conventional process.

A terminal component disclosed herein includes a first metal and a second metal stacked on the first metal. On the first metal, nickel is plated at least on a boundary surface with the second metal. A joining portion joined by diffusion of the metals is formed in a portion of a boundary between the first metal and the second metal.

Disclosed is a copper foil including a copper layer having a matte surface and a shiny surface, and an anticorrosive layer disposed on the copper layer, wherein the copper foil has a residual stress of 0.5 to 25 Mpa, based on absolute value, and the copper layer has a plurality of crystal planes, wherein a ratio [TCR (220)] of a texture coefficient (TC) of (220) crystal plane of the copper layer to a total of texture coefficients (TC) of (111), (200), (220) and (311) crystal planes of the copper layer is 5 to 30%.

A method of manufacturing a metallic cutting member, through electrodeposition, comprises moving a dispenser filled with a metal salt solution to a first printing position, depositing a metal onto a conductive or semi-conductive substrate via the dispenser until the deposited metal contacts the dispenser, and upon detecting that the deposited metal contacts the dispenser, moving the dispenser to a second printing position.
