All-Solid-State Secondary Battery And Production Method Therefor

The present invention provides: an all-solid-state secondary battery, wherein the collapse of a layered body due to a shearing force arising in the peripheral portion thereof when a pressure is applied in the production process can be prevented, and therefore the occurrence of an internal short-circuit can be prevented; and a production method for the all-solid-state secondary battery. The presentinvention is the all-solid-state secondary battery (1) comprising, disposed between a positive electrode collector (11) and a negative electrode collector (21): a layered body (X) resulting from layering a positive electrode layer (12), a solid-state electrolyte layer (32) and a negative electrode layer (22); and a plate-shaped insulation member (41) disposed around this layered body (X), in contact with at least the solid-state electrolyte layer (32), and electrically insulating the positive electrode layer (12) from the negative electrode layer (22). In the insulation member (41), an inneredge portion (41b) in cont
