[0022] First, the film capacitor 1A according to the first embodiment will be described.
[0023] In the present embodiment, the film capacitor 1A corresponds to a "capacitor" described in the claims. In addition, the end surface electrode 11 corresponds to an "electrode" described in the claims. Furthermore, the first exposed portion 21a corresponds to an “exposed portion” described in the claims. Furthermore, the filling resin 40 corresponds to "resin" described in the claims.
[0024] However, the above description is only for the purpose of associating the structure of the claims with the structure of the embodiments, and the invention described in the claims is not limited to the structures of the embodiments through the above correspondence.
[0025] figure 1 (a) is a front cross-sectional view of the film capacitor 1A cut at the positions of the left and right insulation-covered lead wires 20 according to the first embodiment, figure 1 (b) is a right side cross-sect...

[0039] figure 2 (a) is a front cross-sectional view of the film capacitor 1A cut at the positions of the left and right insulation-covered lead wires 20 according to Modification 1, figure 2 (b) is a right side cross-sectional view of the film capacitor 1A cut at the position of the insulation-covered lead wire 20 on the right side according to Modification 1. FIG. figure 2 (c) is a figure for demonstrating the method of making the solder 23 penetrate into the inside of the insulator 22 concerning the modification 1. FIG.
[0040] like figure 2 As shown in (a) and (b), in this modified example, in the lead wire 20, the solder 23 mounted on the first exposed portion 21a of the twisted wire 21 further enters the inside of the insulator 22 and spreads to the insulated body 22. 21 parts of the strands covered. Other configurations are the same as those of the above-mentioned first embodiment.
[0041] In order for the solder 23 to enter the interior of the insulator 22, as...

[0045] image 3 (a) is a front cross-sectional view of main parts of the film capacitor 1A cut at the position of the insulation-covered lead wire 20 according to Modification 2, image 3 (b) is a figure for demonstrating the method of extending the solder 23 attached to the 1st exposed part 21a of the twisted wire 21 to the outer peripheral surface of the insulator 22 concerning the modification 2.
[0046] like image 3 As shown in (a), in this modified example, in the lead wire 20 , the solder 23 attached to the first exposed portion 21 a of the twisted wire 21 further reaches the outer peripheral surface of the insulator 22 on the base end side. In addition, the first exposed portion 21 a of the strand 21 and the end surface electrode 11 are connected by welding the portions of the solder 23 and the end surface electrode 11 that are in contact with each other without using the solder S for connection. Other configurations are the same as those of the above-mentioned firs...
