PURPOSE:To comprise a coil certainly and stably to a printed circuit board by employing the structure that the coil lead of coil wound to a drum type core is connected to the tapered portion of terminal and a cylindrical magnetic alloy material providing a cut-away part for protruding the terminal is loaded to the entire part. CONSTITUTION:A coil 18 is wound to a drum type core 17 embedding terminals, the cut-away part 19a and the gap portion 19b of cylindrical magnetic alloy material 19 are loaded so that they are located at the tapered portions 15b, 16b of terminal from the opposite side of terminal embedding surface of such drum type core 17 and these are fixed with the bonding agent, etc. from the gap portion 19b. The terminals 15, 16 embedded to the terminal grooves 17a, 17b at the external side surface of the one collar of the drum type core 17 are provided with the fixed portions 15a, 16a bonded and combined to the terminal grooves 17a, 17b tapered portions 15b, 16b, and the horizontal portions 15c, 16c protruded to the outside at the end of such tapered portions 15b, 16b. |
