As shown in the figure, a discharge resistor 3 made of carbon or the like is connected between terminals 1 and 2. However, if the discharging resistor 3 is provided outside the case 4, it becomes difficult to attach the capacitor 5 to the equipment.
If the lead wires 6 and 7 of the discharge resistor 3 are long, they tend to come into contact with other parts, which may cause equipment failure.

のテフロン等の合成樹脂が用いられている。 In FIG. 2, 11 is a wound capacitor element, from which lead wires 12 and 13 are drawn out. A case 14 houses the capacitor element 11, and is made of metal such as aluminum or synthetic resin such as epoxy resin. Reference numeral 15 is a lid for sealing the front end of the case 14, and a rubber-covered baking plate is used. 16 and 17 are terminals penetrating through this lid 15, and lead wires 12 and 1, respectively.
3 is connected. A conductive sheet 18 is connected between the terminals 16 and 17 so as to be located on the back side of the lid 15, and has a thickness of several 10 to several 100 μm and a resistance of several tens to several 100 KΩ. A heat insulating sheet 19 is laminated on the conductive sheet 18, and is made of synthetic resin such as Teflon and has a thickness of about 100 μm.

9 may be provided when manufacturing the lid 15, and the manufacturing of the capacitor 20 becomes easy. Moreover, unlike conventional discharge resistors, the end face of the capacitor element 11 is not damaged. In addition, since the thickness of the conductive sheet 18 and the heat shield sheet 19 is as thin as μ units, case 1
4 also does not need to be made large and can be made smaller.
Furthermore, although the conductive sheet 18 generates heat during discharge, since the heat insulating sheet 19 is provided, heat is not directly transferred to the capacitor element 11, and thermal deterioration of the capacitor can be reduced.

Moreover, it can be easily attached to electrical equipment without mistakes.
