    摘要: A method for producing a film capacitor, the method including a sealing material supplying step of supplying a curable sealing material 30a to an element accommodating space 20a in which a film capacitor element 10 having a rolled body 12 is accommodated; and a curing step of curing the sealing material 30a in a state in which the rolled body 12 is embedded in the sealing material 30a, in which at the time of initiating the sealing material supplying step, the rolled body 12 is not fixed by the sealing material 30a, and in the sealing material supplying step, the sealing material 30a is supplied to the element accommodating space 20a without curing the sealing material 30a, from the beginning of the supply of the sealing material 30a to the element accommodating space 20a until the rolled body 12 is embedded in the sealing material 30a.
