摘要

Provided are a metal plate configured such that sufficient strength and performance are ensured and the workability and cost of mass production are improved, and a metal-supported electrochemical element and the like including the metal plate. A metal plate 1 is formed by stacking a plurality of thin metal plates 10 and 20. The thin metal plates 10 and 20 are respectively provided with a plurality of through holes 10c and 20c passing therethrough in the thickness direction. The metal plate 1 is provided with penetration spaces 1c formed by the through holes 10c and 20c of the plurality of thin metal plates 10 and 20 that are in communication with each other in a state in which thin metal plates 10 and 20 are stacked. A metal plate aspect ratio that is a value obtained by dividing the thickness of each of the thin metal plates 10 and 20 by the inner diameter of the through holes 10c and 20c is 2 or less. A metal support aspect ratio that is a value obtained by dividing the overall thickness of the metal plate 1 by the minimum inner diameter of the penetration spaces 1c is 3 or more.
