Abstract: An all-solid-state secondary battery includes a positive electrode layer (2) and a negative electrode layer (4) that are disposed on a positive electrode current collector (1) and a negative electrode current collector (5), respectively, and are pressurized thereon, and a solid electrolyte layer (3) interposed between the positive electrode layer (2) and the negative electrode layer (4). The positive electrode layer (2) and the negative electrode layer (4) contain a sulfide inorganic solid electrolyte, and the positive electrode current collector (1) and the negative electrode current collector (5) have a peel strength of at least 0.2 N/mm relative to the sulfide inorganic solid electrolyte in a peel test.
