Abstract
What is provided is a solid state battery which can be manufactured with a high yield, has little variation in initial performance, and has a long lifespan and a method of manufacturing the same. A solid state battery includes a flat laminated structure which is obtained by winding an electrode laminated sheet extending from a first end to a second end. In the electrode laminated sheet, a first sheet and a second sheet are disposed while a first connection portion and a second connection portion face each other in a plan view, a first region in which a first solid electrolyte sheet, a first electrode, a second solid electrolyte sheet, and a second electrode piece are laminated in this order and a second region in which a second electrode piece, a first solid electrolyte sheet, a first electrode, and a second solid electrolyte sheet are laminated in this order are alternately formed in a longitudinal direction between the first connection portion and the second connection portion, and the electrode laminated sheet is wound around the first end so that the first electrode and the second electrode piece are alternately laminated so as to overlap each other in a plan view.
