ALL-SOLID-STATE SECONDARY BATTERY AND PRODUCTION METHOD THEREFOR

The present invention provides an all-solid-state secondary battery and a method for producing the same, wherein it is possible to prevent the collapse of a laminate due to a shearing force occurring in the peripheral portion of the laminate when the laminate is pressed in the production process, and therefore it is possible to prevent the occurrence of an internal short circuit. The present invention is the all-solid-state secondary battery (1) including a laminate (X) and a plate-shaped insulating member (41) both arranged between the positive electrode collector (11) and the negative electrode collector (21). The laminate (X) includes a positive electrode layer (12), a solid electrolyte layer (32), and a negative electrode layer (22) stacked together. The plate-shaped insulating member (41) is arranged around the laminate (X) and contacted at least with the solid electrolyte layer (32) to electrically insulate the positive electrode layer (12) and the negative electrode layer (22) from each other. In the insulating member (41), a contact inner edge portion (41b) contacted with the laminate (X) has a larger thickness than a plate-shaped portion (41a) positioned on the outer side.
