Abstract
A surface-mounted inductor including a coil having a wound part formed by winding a conductive wire and extended parts extended from an outer circumference of the wound part, a molded body containing the coil, constituted by a composite material containing a magnetic powder, and outer terminals connected to end portions of the extended parts disposed on a mounting surface. The wound part is contained within the molded body so that a winding axis is parallel to the mounting surface. The extended parts are extended toward the mounting surface side, each end portion of the extended parts are exposed from the surface thereof of the molded body. In the molded body, a density of a magnetic powder between the end portions of the extended parts on the mounting-side surface is lower than a density in the surface on the opposite side from the mounting surface.
