Abstract

This invention discloses a voltage-resistant capacitor device comprising a positive conductive layer, a first insulating layer, a negative conductive layer, a second insulating layer, a gap layer, and an insulating material. The positive conductive layer is connected to a positive terminal. The first insulating layer is disposed on the positive conductive layer, forming a first thin film layer. The negative conductive layer is connected to a negative terminal. The second insulating layer is disposed on the negative conductive layer, forming a second thin film layer, which is disposed on the first thin film layer and wound around it. A gap layer is formed between the first and second thin film layers. The insulating material is disposed in the gap layer.
