Abstract

A coil apparatus capable of insulating a one-turn coil from an adjacent member while requiring a small number of members. In the coil apparatus according to the present invention, a retaining piece is formed at one end and a pair of coil terminals are formed at another end of a round coil constituted of a metal plate. A fitting wall at which the coil main body is fitted and first and second retaining portions formed by notching two portions of the fitting wall facing opposite each other are formed in the insulating case. The coil main body is fitted at the fitting wall of the insulating case, the coil terminals at one end of the coil are retained at the first retaining portion as the coil is turned and the coil is insulated from the core by retaining the retaining piece at the second retaining portion and thus preventing the coil from becoming lifted. The center of the coil constituted of a metal plate is aligned on a line extending from the central line passing the center of one of the pair of coil terminals along the widthwise direction.
