A formed body incorporating a coil by using: a coil formed by winding a conductive wire, and a formed body incorporating the coil, the formed body being formed with a sealing material containing a resin and a magnetic material. The coil is formed by winding the conductive wire so that lead-out ends are positioned at an outer periphery of a wound portion. The formed body is formed so that surfaces of the coil are partially exposed on four side surfaces of the formed body which are parallel to a winding axis of the coil, and the area of a portion of the formed body outside the outer periphery of the wound portion is almost equal to or smaller than the area of a portion of the formed body inside an inner periphery of the wound portion of the coil.

Manufacturing method for surface mounted inductor

Surface mounted inductor and manufacturing method therefor

[Technical Problem] This invention provides a surface-mount inductor that is capable of positioning a coil in a predetermined position in a mold, thereby to position the coil in a predetermined position of a core and to prevent led-out ends from being buried in the core. [Solution to the Problem] A surface-mount inductor of the present invention comprises: a coil formed by winding a winding wire; and a core containing a magnetic powder and including the coil therein. The coil has opposite led-out ends, each of which is exposed on respective ones of opposed side surfaces of the core. Each of the led-out ends of the coil is connected to an external electrode formed on the core.
