A metal support for an electrochemical element has a plate shape as a whole, and is provided with a plurality of penetration spacesthat pass through the metal support from a front faceto a back face. The front faceis a face to be provided with an electrode layer. A region of the front faceprovided with the penetration spaces is a hole region, and openings of the penetration spaces formed in the front face are front-side openings. An aperture ratio that is a ratio of the front-side openings to the hole region is 0.1% or more and 7.0% or less.

Metal support for electrochemical element, electrochemical element, electrochemical module, electrochemical device, energy system, solid oxide fuel cell, solid oxide electrolytic cell, and method for manufacturing metal support

A metal support for an electrochemical element where the metal support includes a plate face, has a plate shape as a whole, and has a warping degree of 1.5×10or less determined by calculating a least square value through the least squares method using at least three points in the plate face of the metal support, calculating a first difference between the least square value and a positive-side maximum displacement value on a positive side with respect to the least square value and a second difference between the least square value and a negative-side maximum displacement value on a negative side that is opposite to the positive side with respect to the least square value, and dividing the sum of the first difference and the second difference by a maximum length of the plate face of the metal support that passes through a center of gravity.
