To provide a manufacturing method of an all-solid battery that can suppress chipping at the cut end, dropout of constituent materials, etc., and suppress peeling of a solid electrolyte layer.SOLUTION: A manufacturing method of an all-solid battery includes a step of preparing a first laminated body 101 in which a first solid electrolyte layer 2 is laminated on a first active material layer 1, a step of forming a solid electrolyte layer removing portion 20 formed by removing a part of the first solid electrolyte layer 2 on the first active material layer 1, and a step of irradiating the solid electrolyte layer removing portion 20 with a laser beam L in the stacking direction of the first laminated body 101 to cut the first laminated body 101.SELECTED DRAWING: Figure 1 【課題】裁断端における欠けや構成材料の脱落等を抑制し、かつ固体電解質層の剥離を抑制できる、全固体電池の製造方法の提供。【解決手段】第１の活物質層１上に第１の固体電解質層２を積層した第１の積層体１０１を準備する工程と、前記第１の活物質層１上の前記第１の固体電解質層２の一部を除去してなる固体電解質層除去部２０を形成する工程と、前記固体電解質層除去部２０に、前記第１の積層体１０１の積層方向にレーザー光Ｌを照射して、該第１の積層体１０１を裁断する工程とを有する全固体電池の製造方法。【選択図】図１
