To provide an all-solid battery pack in which a part with a large heat generation quantity can be cooled with priority.SOLUTION: An all-solid battery pack 100 includes a first all-solid battery 10a, a second all-solid battery 10b, and a cooling device 30. Each of the first all-solid battery 10a and the second all-solid battery 10b includes: an electrode body 11 including a plurality of first current collector foils 11a and second current collector foils 11b that are alternately stacked along a first direction DR1, and a solid electrolyte layer 11c between the first current collector foil 11a and the second current collector foil 11b; a case 12 that houses the electrode body 11; a first terminal 13 connected to the first current collector foil 11a and extending from a peripheral part 12a of the case 12 when viewed from the first direction DR1 along a second direction DR2 intersecting with the first direction DR1; and a second terminal 14 connected to the second current collector foil 11b and extending from the peripheral part 12a along the second direction DR2.SELECTED DRAWING: Figure 1 【課題】発熱量が大きい部分を優先的に冷却することが可能な全固体電池パックを提供する。【解決手段】全固体電池パック１００は、第１全固体電池１０ａ及び第２全固体電池１０ｂと、冷却装置３０とを備える。第１全固体電池１０ａ及び第２全固体電池１０ｂは、それぞれ、第１方向ＤＲ１に沿って交互に積層されている複数の第１集電箔１１ａ及び第２集電箔１１ｂと、第１集電箔１１ａと第２集電箔１１ｂとの間にある固体電解質層１１ｃとを含む電極体１１と、電極体１１を収容しているケース１２と、第１集電箔１１ａに接続されており、第１方向ＤＲ１から見た際のケース１２の周縁部１２ａから第１方向ＤＲ１に交差している第２方向ＤＲ２に沿って延出している第１端子１３と、第２集電箔１１ｂに接続されており、周縁部１２ａから第２方向ＤＲ２に沿って延出している第２端子１４とを有している。【選択図】図１
