PROBLEM TO BE SOLVED: To provide a laminated film sheathed battery in which a force loaded on electrode groups and heat conduction when heated and sealed can be suppressed, and in which inside short-circuit is reduced. SOLUTION: In the laminated film sheathed battery 1, the outer rim of the sheathed body of the laminated film 2 is thermally fused. In the sheathed body, the electrode groups 10 in which the positive electrodes and the negative electrodes are laminated via a separator and a framed state resin frame 5 to protect the electrode groups 10 are sealed. In the one side of the resin frame 5, a groove part of a roughly U-shaped cross-section is formed in the one face side in the height direction, and into the groove, the electrode terminal is fitted. The electrode terminal is fixed to the outer rim part of the laminated film 2, and taken out to the outside of the laminated film sheathed battery 1. The height h of the resin frame 5 is in the range of 90-110% of the thickness a of the electrode groups. Even if external force is applied, the resin frame 5 protects the electrode groups 10.
