摘要

An object of the present invention is to provide an electrochemical element and the like with which sufficient strength and performance are ensured, and the workability and cost of mass production are improved. A metal support 1 for an electrochemical element has a plate shape as a whole, and is provided with a plurality of penetration spaces 1c that pass through the metal support from a front face 1a to a back face 1b. The front face 1a is a face to be provided with an electrode layer. Each of front-side openings 1d that are openings of the penetration spaces 1c formed in the front face 1a has an area of 3.0×10^-4 mm² or more and 3.0×10^-3 mm² or less.
