To provide a battery capable of increasing the capacity while suppressing deterioration of input/output characteristics and reliability.SOLUTION: A battery 1000 comprises a positive electrode current collector layer 100, a negative electrode current collector layer 300, and a power generation layer 200. The power generation layer 200 includes a solid electrolyte layer 600, a positive electrode active material part 400, and a negative electrode active material part 500. The positive electrode active material part 400 is electrically connected with the positive electrode current collector layer 100. The negative electrode active material part 500 is electrically connected with the negative electrode current collector layer 300. A length in a thickness direction of the power generation layer 200 of the positive electrode active material part 400 and the negative electrode active material part 500 is longer than half a thickness of the power generation layer.SELECTED DRAWING: Figure 1 【課題】入出力特性及び信頼性の低下を抑制しつつ大容量化が可能な電池を提供する。【解決手段】電池１０００は、正極集電体層１００、負極集電体層３００、及び発電層２００を備える。発電層２００は、固体電解質層６００、正極活物質部４００、及び負極活物質部５００を含む。正極活物質部４００は、正極集電体層１００と電気的に接続する。負極活物質部５００は、負極集電体層３００と電気的に接続する。正極活物質部４００および負極活物質部５００の発電層２００の厚み方向における長さは、前記発電層の厚みの半分よりも長い。【選択図】図１
