1. An electrochemical module comprising:
a stack obtained by stacking, in a predetermined stacking direction, a plurality of electrochemical elements having a configuration in which an electrolyte layer, and an electrode layer and a counter electrode layer that are respectively arranged on two sides of the electrolyte layer, are formed along a substrate via an annular sealing portion through which a first gas, which is one of a reducing component gas and an oxidative component gas, flows;
a clamp comprising a first clamping portion for pressing a first flat face in the stacking direction of the stack and a second clamping portion for pressing a second flat face on a side opposite to the first flat face, the stack clamped between the first clamping portion and the second clamping portion; and
an elastic first plate-like member arranged between the first flat face and the first clamping portion; and
a flowing pipe connected to the second flat face in a state of being in communication with the annular sealing portion; and
further comprising an elastic second plate-like member arranged between the second flat face and the second clamping portion,
wherein an elastic force of the first plate-like member is larger than an elastic force of the second plate-like member.
