  "textContent": "A lid body includes a terminal member of at least one of a positive electrode and a negative electrode, a sealing plate including an attachment hole for attaching the terminal member, and a sealing material containing a thermoplastic resin and an inorganic filler. The terminal member is inserted into the attachment hole and attached to the sealing plate in a state in which the sealing material is joined to a peripheral portion of the attachment hole. Here, as the inorganic filler, an inorganic substance having a volume change rate of 20% or less after being immersed for 7 days in a test electrolyte, which is prepared at 65° C., and which contains 1200 ppm of water and 1 M of LiPF, and moreover in which a volume ratio of a solvent thereof satisfies a relationship of ethylene carbonate:diethyl carbonate:dimethyl carbonate=1:1:1, is used.",
