PROBLEM TO BE SOLVED: To provide a flat type battery having a laminate housed in an internal space formed by an outer can and a mouth sealing can, said battery having a structure capable of preventing the laminate from being damaged by a gasket when the outer can and the mouth sealing can are combined.SOLUTION: A flat type battery (1) comprises: a cathode can (10) having a peripheral wall section (12); an anode can (20) having a peripheral wall section (22); an electrode body (40) formed by stacking a cathode (41) and an anode (46) one on top of another in the thickness direction and housed in an inner space (1a); and a gasket (30) sandwiched between the cathode can (10) and the anode can (20). The gasket (30) includes a gasket interior part (31) positioned within the inner space (1a). The gasket interior part (31) has an R section (31a) provided on the inner side of the inner space (1a) and on the bottom (11) side of the cathode can (10). |
