ASSEMBLY INCLUDING UNIT CELL AND SPACER

A unit cell including a cell body, an electrode tab (an anode side electrode tab and a cathode side electrode tab) and a sealing member (laminate film). The cell body includes a power-generating element and is formed into a flat shape. The anode side electrode tab and the cathode side electrode tab extend out from the cell body. The sealing member (laminate film) includes a sheet-shaped metal layer and a sheet-shaped insulating layer that covers and insulates the metal layer from both sides to sandwich and seal the cell body. In the sealing member, an exposed end portion of a metal layer is spaced from a surface of the insulating layer, while bending at least a portion of an outer edge.
