摘要： An all-solid-state battery includes: a laminate in which a positive electrode active material layer, a solid electrolyte layer, and a negative electrode active material layer are laminated in this order; a positive electrode current collector and a negative electrode current collector which sandwich the laminate in a laminating direction; an insulating sheet which surrounds the laminate between the positive electrode current collector and the negative electrode current collector; and a first adhesive sheet which bonds the insulating sheet and the positive electrode current collector or the insulating sheet and the negative electrode current collector, wherein a first through-hole is formed in the first adhesive sheet and the laminate is accommodated in the first through-hole when viewed from the laminating direction of the laminate.

摘要： An all-solid-state battery includes a positive electrode layer including a positive electrode active material layer and a positive electrode current collector; a negative electrode layer including a negative electrode active material layer and a negative electrode current collector; a solid electrolyte layer; and an insulating film, in which the insulating film has therein a through-hole in which a laminate in which the positive electrode active material layer, the solid electrolyte layer, and the negative electrode active material layer are sequentially stacked is housed, the laminate and the insulating film are arranged between the positive electrode current collector and the negative electrode current collector, and an external shape of the insulating film is larger than external shapes of the positive electrode current collector and the negative electrode current collector when viewed in a plan view in a laminating direction of the laminate.
