To provide a battery with a flat electrode, wherein a pressurizing force can be applied between the electrode and an electrolytic layer with a simple configuration and performance deterioration can be suppressed.
An electric power accumulating part B has such a structure that a positive electrode member 1 and a negative electrode member 2 are alternately stacked with a solid electrolytic layer 3 therebetween. The positive electrode member 1 and the negative electrode member 2 have a structure of both-side film formation type in which a positive electrode 1b and a negative electrode 2b are formed on both surfaces of current collectors 1a and 2a. The solid electrolytic layer 3 is interposed between the positive electrode 1b and the negative electrode 2b. A ceiling part 15a of a cap 15 is deformed downward in protruded manner in advance. The positive electrode member 1, the negative electrode member 2, and the solid electrolytic layer 3 are pressurized with a substrate 13 and the ceiling part 15a, so that the positive electrode 1b and negative electrode 2b are surely brought into contact with the solid electrolytic layer 3, thereby suppressing increase in power loss and reduction in battery capacitance.
