し、蓋締めを行う。(Embodiment 2) In FIG. 3, when the inner case 1 made of polypropylene resin is provided with an arcuate convex portion 10 in the opening, the inner case 1 is inserted into the metal case 3 as shown in FIG. The spring force of the convex portion 10 of the inner case is used in advance to temporarily hold it in the middle so that the lead piece 5 is located above the upper end opening 6 of the metal case 3 when the capacitor element 4 is inserted. . In this state, it is connected to the terminal fitting 9 provided on the lid 8 in FIG. After that, the capacitor element 4,
