摘要： 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.

摘要： A manufacturing method of a surface mounted inductor involves using a coil and a tablet in a molding die. The coil is placed on the tablet. The coil and the tablet are arranged in the molding die and pressurized and compressed to the size of the cavity in the molding die at a first temperature. The coil and the tablet are pressurized in the molding die at a second temperature higher than the first temperature to form a formed body incorporating the coil.
