The invention provides a solid-state battery, a method for manufacturing the solid-state battery, and an apparatus for manufacturing the solid-state battery. The disclosed manufacturing method includes a step (i) and a step (ii) in this order. Step (i) is a step for preparing a laminate (100) that includes: a power generation element (110) that includes a positive electrode layer (111), a negative electrode layer (112), and a solid electrolyte layer (113) that is arranged between the positive electrode layer (111) and the negative electrode layer (112); and at least one metal foil (121) disposed on at least one main surface of the power generation element (110). Step (ii) is a step in which the power generation element (110) is divided at a linear division position (100d) and at least one metal foil (121) is cut at the division position (100d). 本发明提供固态电池、固态电池的制造方法以及固态电池的制造装置。公开的制造方法依次包括工序(i)以及工序(ii)。工序(i)是准备层叠体(100)的工序，所述层叠体(100)包括：发电元件(110)，包括正极层(111)、负极层(112)以及配置在正极层(111)与负极层(112)之间的固态电解质层(113)；以及至少一个金属箔(12
