Abstract
A surface-mounted-type inductance element comprising a coil structure having a bobbin; the bobbin including a portion around which wires are coiled, a pair of flanges integrally formed at opposing ends of the bobbin, a pair of bases integrally formed at lower edge portions of the flanges in a manner to project laterally from the flanges, and a plurality of external terminals attached to each of the bases in a manner to penetrate the base, each the external terminal including a first portion projecting laterally from the base and a second portion projecting downward from the base, around which first portion of each the external terminal a termination of any one of the wires is wound; a mold covering the coil structure in a manner to allow the second portions of the external terminals to be projected outward from the mold, the mold being formed of resin material exhibiting heat resistance; and a pair of cores assembled to the coil structure through the mold.
