Abstract
[Problem to be Solved] To provide a helical capacitor for controlling a high-frequency power which flows in power lines, and a manufacturing method of the helical capacitor. [Solution] A helical capacitor is constituted by helically spiraling a belt shape capacitor linewhich includes an internal metal body to be a helically spiraled belt-shape internal electrical conductor, a dielectric film covering the internal electrical conductor, and an electrically conductive layer covering the dielectric film. The capacitor line of belt shapecan be wrapped around the internal support body. Internal metal body lead terminalsare respectively formed at both ends of the internal metal body, and electrically conductive layer lead terminals,can be respectively formed at both ends of the electrically conductive layer.
