Abstract:
     Provided is a surface mount inductor wherein the break of its wrapping terminal, etc. are not generated, and the disconnection of the terminal of its winding caused by the edges of its wrapping terminal is hardly generated, and further, the reduction of its height is made possible. The surface mount inductor has a drum core 2, a coil 3 wound around a wound-axis portion 21 of the drum core 2, a case 4 of a non-conductive member which is disposed in the periphery of the coil 3, each wrapping terminal 13 fastened to the case 4 and so protruded in the outside radial direction of the case 4 as to wrap each terminal of the winding 3 to it, and each metal terminal member 5 having each plane terminal 11 to be each contact portion with a board when the inductor is mounted on the surface of the board. In this surface mount inductor, there is so provided each extended portion 6 which is extended from the case 4 in the outside radial direction of the case 4, and is disposed in the position of it overlapping with each bound terminal 13 in the height direction of the drum type core 2, and further, has its width wider than the width of the bound terminal 13 or nearly equal thereto as to wind each terminal of the coil 3 around both outer peripheries of the wrapping terminal 13 and the extended portion 6.
