摘要

Provided is an electrochemical device and the like having improved processability and cost during mass production while ensuring sufficient strength and performance. A metal support 1 of the electrochemical device has a plate shape as a whole, and has a plurality of penetrating spaces 1c penetrating from a front side 1a to a back side 1b, with the surface on which an electrode layer is formed serving as the front side 1a. The area of a front side opening 1d which is the opening of the front side 1a of the penetration space 1c is 3.0 × 10^-4 mm² or more and 3.0 × 10^-3 mm² or less.
