Abstract

PURPOSE:To obtain a compact inductance with a uniform and stable inductance value by a method wherein a number of elements are manufactured en block by providing them with such structure that does not need winding work. CONSTITUTION:An insulating sheet 3 is divided into the plural number of sections 3a-3e in a longitudinal direction, and coils with the windings required can be formed when the sheet is folded in a zigzag shape according to dividing lines 7 which divide the sheet into the plural number of sections 3a-3e. In other words, the sections 3a, 3e in both the end portions of the sheet 3 are provided with coil terminals 5, 6, and each sections 3a-3d connecting these coil terminals 5, 6 is linked with a half-wound coil conductor 4a-4d reciprocally in an opposite direction so as to form a coil member 14. Each of the half-wound coil conductors 4a-4d are connected with each other by the conductors 41-43, and the connection of the coil terminals 5, 6 with the half-wound coil conductors 4a, 4d is made by conductors 40 and 40'.
