发明名称 Coil component, transformer, switching power supply unit, and method for manufacturing coil component
摘要 <p>A coil component includes coil windings, and resin portions that are insulating members having electrical insulation properties and integrally formed with the coil windings covering parts of surfaces of the coil windings, and the coil component is sandwiched by magnetic core members in directions of winding axes of the coil windings. The coil windings are composed of a plurality of plate-like coil members in a ring shape having ends joined in a stacking direction with a clearance therebetween to be continuous in a predetermined winding direction. The resin portions that are the insulating members cover outermost plate surfaces of the coil members facing the magnetic core members, a space between the adjacent coil members, and inner perimeter edges of the coil members, and have openings along the directions of winding axes of the coil windings.</p>
