This electrochemical cell device is provided with: a cell having a first main surface and a second main surface which is a surface facing the first main surface; a first current collector having a third main surface facing the first main surface; and a second current collector having a fourth main surface facing the second main surface. The battery is warped convexly from the second main surface toward the first main surface. The third main surface includes a recessed portion at a position facing a center portion of the first main surface. The fourth main surface includes a convex portion at a position facing a center portion of the second main surface. Each of the first current collector and the second current collector is composed of at least one metal porous body sheet, and the at least one metal porous body sheet is composed of a metal porous body having a skeleton having a three-dimensional mesh structure. The center portion of the first main surface includes a portion of the first main surface having th
