Zusammenfassung:	A lid body including: a terminal member of at least one electrode; a sealing plate having a mounting hole for attaching the terminal member; and a sealing material containing an inorganic filler. The terminal member is inserted into the mounting hole and is attached to the sealing plate in a state where the sealing material is joined to a peripheral edge portion of the mounting hole. In a microscope observation of a cross section of the sealing material, an average aspect ratio of the inorganic filler is 2 or higher, and with an average orientation angle of the inorganic filler is 30 degrees or smaller, in at least the sealing material formed on an outer surface of the sealing plate.
