  "textContent": "To provide a reliable coin-type battery whose capacity is increased without impairing sealing properties by enlarging a housing space for housing an electrode body and a method for manufacturing the coin-type battery. A coin-type battery 1 includes a positive electrode can 10, a negative electrode can 20, and a resin film 30 at least partially disposed between a peripheral wall portion 12 of the positive electrode can 10 and a side wall portion 22 of the negative electrode can 20, and a power generation element 40. The resin film 30 is an annular body having a cylindrical shape and including a film peripheral wall portion 31 disposed between the peripheral wall portion 12 of the positive electrode can 10 and the side wall portion 22 of the negative electrode can 20, and a film bottom portion 32 disposed between a bottom portion 11 of the positive electrode can 10 and the open end portion 23 of the side wall portion 22 of the negative electrode can 20.",
