摘要

The purpose of the present invention is to provide an electrochemical element, etc., in which cost and workability for mass production are improved while ensuring sufficient strength and performance. A metal support body 1 for an electrochemical element has a plate shape overall, and has a plurality of penetrating spaces 1c penetrating from an obverse side surface 1a to a reverse side surface 1b, with the obverse side surface 1a being the surface on which an electrode layer is provided. The region of the obverse side surface 1a in which the penetrating spaces 1c are formed is deemed to be a hole region 1g. The opening parts of the penetrating spaces 1c on the obverse side surface 1a are deemed to be obverse side opening parts 1d. The opening ratio, which is the proportion of the hole region 1g occupied by the obverse side opening parts 1d, is 0.1 to 7.0% inclusive.
