ALL-SOLID BATTERY AND METHOD OF MANUFACTURING THE SAME

To suppress occurrence of warpage in an all-solid battery.SOLUTION: An all-solid battery comprises: a laminate in which a plurality of first electrode layers, a plurality of solid electrolyte layers, and a plurality of second electrode layers are laminated in a first direction, and that has a first surface on which the first electrode layers appear and a second surface on which the second electrode layers appear; a first external electrode provided on the first surface so as to be connected with the first electrode layers; and a second external electrode provided on the second surface so as to be connected with the second electrode layers. Each first electrode layer has: a first portion connected with the first external electrode; and a second portion extending in a second direction from the first external electrode toward the second external electrode. A first width of the first portion in a third direction crossing the first and second directions respectively is wider than a second width of the second portion.SELECTED DRAWING: Figure 4 【課題】全固体電池に反りが発生するのを抑制すること。【解決手段】第１の電極層、固体電解質層、及び第２の電極層の各々が第１の方向に沿って複数積層され、前記第１の電極層が表出する第１の面と、前記第２の電極層が表出する第２の面とを備えた積層体と、前記第１の面に設けられ、かつ前記第１の電極層に接続された第１の外部電極と、前記第２の面に設けられ、かつ前記第２の電極層に接続された第２の外部電極とを有し、前記第１の電極層は、前記第１の外部電極に接続された第１の部分と、前記第１の外部電極から前記第２の外部電極に向かう第２の方向に沿って延びる第２の部分とを有し、前記第１の方向と前記第２の方向の各々と交叉する第３の方向に沿った前記第１の部分の第１の幅が前記第２の部分の第２の幅よりも広いことを特徴とする。【選択図】図４
