The sealing body (30) includes a sealing plate (31) that is electrically connected to the positive electrode (11), and a positive electrode terminal (32) that is disposed on the sealing plate (31) and is electrically connected to the sealing plate (31). The sealing plate (31) has a first surface facing toward the electrode body (14), and a second surface positioned on the axially opposite side from the first surface. The positive electrode terminal (21) is disposed on the second surface. The sealing plate (31) deforms in a direction away from the electrode body (14) in the axial direction P when the pressure within the case (20) increases. A holding part that covers the outer peripheral surface of the positive electrode terminal (32) and holds the positive electrode terminal (32) is formed on the second surface of the sealing plate (31).",
