PROBLEM TO BE SOLVED: To provide a lamination-type unit cell having high reliability. SOLUTION: The lamination-type unit cell houses an electrode body in a laminated film outer package, the electrode body including a sheet-like positive electrode connected to a positive electrode external terminal; a sheet-like negative electrode connected to a negative electrode external terminal; and a separator. The laminated film outer package is constituted of two metal laminated films, or one metal laminated film folded into two; the peripheral portion of the laminated film outer package is heat-sealed, in a state such that the positive electrode external terminal and the negative electrode external terminal are extracted to the outside from the peripheral portion of the laminated film outer package; and at least a portion of a heat-sealing portion in the peripheral portion of the laminated film outer package is covered with resin for reinforcement.
