Abstract
An inductor using a rectangular wire wound in an axial direction roughly parallel with a mounted substrate, and enabling an increase in connection strength in mounting. The inductor (10) comprises a core member (20) formed of a magnetic material, the rectangular wire (30) formed in a flat shape so that the contact faces thereof are positioned along the longitudinal direction and forming winding structures (31) by winding them on the outer peripheral surface of the core member (20) by edgewise winding, and a case body (40) in which the core member (20) and the rectangular wire (30) are disposed. The rectangular wire (30) is wound, by multiple turns, on the core member (20), and the multiple winding structures (31) are disposed, in a stacked state, along the axial direction of the core member (20).
