Kind Code:
A1
Abstract:
This film capacitor manufacturing method involves a sealing material supply step for supplying a curable sealing material 30a to an element housing space 20a in which a film capacitor element 10 having a wound body 12 is housed, and a curing step for curing the sealing material 30a in a state in which the wound body 12 is embedded in the sealing material 30a. At the start of the sealing material supply step, the wound body 12 is not fixed by the sealing material 30a; in the sealing material supply step, from the start of supplying the sealing material 30a into the element housing space 20 until the wound body 12 is embedded in the sealing material 30a, the sealing material 30a is supplied to the element housing space 20a without curing the sealing material 30a.
