Abstract
PURPOSE: To make easier assembly and to greatly raise producibility by holding spirally wound elastic metal magnetic thin plate inside a magnetic core case by making use of the elastic rewinding force of the thin metal plate.
CONSTITUTION: The elastic metal magnetic thic plate 7, as, for example, of a noncrystal magnetic alloy containing iron, nickel, and cobalt as the main components, together with boron and silicon, is spirally wound around the core 8 until an appropriate outside diameter is reached. Then, after the metal thin plate is cut, the end portion 9 is fixed with the fixing tool 10 and then inserted into the magnetic core case 15 made of a cylindrical insulating material. Subsequently, when the fixing tool 10 is removed, the metal magnetic thin plate 7 rewinds by virtue of its own wlasticity to internally contact with the inner surface of the case 15, thus ensuring the holding of the magnetic core 16 inside the case 15
