摘要

Provided are an electrochemical element and the like that have both durability and high performance as well as excellent reliability. The electrochemical element includes a metal support, and an electrode layer formed on/over the metal support. The metal support is made of any one of a Fe-Cr based alloy that contains Ti in an amount of 0.15 mass% or more and 1.0 mass% or less, a Fe-Cr based alloy that contains Zr in an amount of 0.15 mass% or more and 1.0 mass% or less, and a Fe-Cr based alloy that contains Ti and Zr, a total content of Ti and Zr being 0.15 mass% or more and 1.0 mass% or less.
