An electrochemical cell includes a support body, a first electrode layer, an electrolyte layer, and a second electrode layer. The first electrode layer is disposed on the support body. The electrolyte layer is disposed on the first electrode layer. The second electrode layer is disposed on the side opposite to the first electrode layer with respect to the electrolyte layer. The support has a current collecting layer, a beam portion embedded in the current collecting layer, and a through hole that penetrates along a stacking direction from a first main surface opposite to the first electrode layer to a second main surface facing the first electrode layer.
