<p>PURPOSE:To provide a coil part for various electronic equipment which realizes miniaturization, high reliability, and high productivity. CONSTITUTION:As a central magnetic leg to be built in the center of a wiring 18, an I-shaped laminate core 16 having a triangular section with tapered surfaces 15 on both ends is used. As the magnetic leg on both sides, a pair of a C-shaped laminate core 20 having on both ends a tapered surface 19 which fits one tapered surface 15 of the tapered surfaces 15 of the triangular section of the I-shaped laminate core 16 are used, its construction being the wiring 18 wound around a core molded with an insulator of uniform thickness except for fitting tapered surfaces 15 and 19. This realizes the miniaturization, high reliability, and high productivity of a coil.</p> |
