Abstract

This collector plate includes a peripheral edge wall that surrounds a predetermined region, and is provided on at least one surface of the collector plate, in which a surface roughness (Ra) of a first surface which is an exposed surface of the peripheral edge wall on the side of one surface, which is measured along a direction perpendicular to an extension direction of the peripheral edge wall is greater than a surface roughness (Ra) of the first surface which is measured along the extension direction of the peripheral edge wall.
