An electrochemical element including a plate-like support provided with an internal passage therein. The plate-like support includes a gas-permeable portion through which gas is permeable between the internal passage and the outside of the plate-like support and an electrochemical reaction portion that is formed by stacking at least a film-like electrode layer, a film-like electrolyte layer, and a film-like counter electrode layer in the stated order in a predetermined stacking direction on an outer face of the plate-like support so as to entirely or partially cover the gas-permeable portion. A first gas, that is one of reducing component gas and oxidative component gas, flows through the internal passage, and the internal passage is provided with a turbulence forming body that forms a turbulence state of the first gas.

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.
