All-solid-state battery

An all-solid-state battery comprising a laminate in which:

• a positive electrode layer including a positive electrode current collector layer and a positive electrode active material layer;
• and a negative electrode layer including a negative electrode current collector layer and a negative electrode active material layer, are alternately laminated with a solid electrolyte layer interposed therebetween, wherein
• the positive electrode layer includes a first positive electrode end portion exposed on a first side surface of the laminate and a second positive electrode end portion not exposed on a second side surface on a side opposite to the first side surface,
• the negative electrode layer includes a first negative electrode end portion exposed on the second side surface of the laminate and a second negative electrode end portion not exposed on the first side surface of the laminate, and
• the laminate includes at least one of a first uneven part formed on the first side surface of the laminate and a second uneven part formed on the second side surface of the laminate,
• the laminate includes a third side surface positioned to a lateral side of the first side surface and the second side surface,
• the positive electrode layer includes a third positive electrode end portion positioned to a lateral side of the first positive electrode end portion and the second positive electrode end portion and configured to be exposed on the third side surface,
• the negative electrode layer includes a third negative electrode end portion positioned to a lateral side of the first negative electrode end portion and the second negative electrode end portion and configured to be exposed on the third side surface, and
• a third uneven part is provided to be formed on the third side surface of the laminate.
