Abstract
Realized is an element having an electrolyte layer that is dense and has high gas barrier characteristics. A metal-supported electrochemical element includes at least a metal substrate as a support, an electrode layer formed on/over the metal substrate, a buffer layer formed on the electrode layer, and an electrolyte layer formed on the buffer layer. The electrode layer is porous and the electrolyte layer is dense. The buffer layer has density higher than density of the electrode layer and lower than density of the electrolyte layer.
