Abstract: 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.
