Abstract
There are provided a coil-embedded dust core that provides high inductance and a method for manufacturing the same. The coil-embedded dust core includes a coilformed by winding a flat conductorand a green bodycomprising of ferromagnetic metal powder coated with an insulating material. The coilis composed of a winding sectionin which the flat conductorhaving front and back surfaces opposed to each other with a predetermined distance is wound and lead-out end sectionsandthat are extended from the winding section. Either one of the front and back surfaces of the lead-out end sectionand either one of the front and back surfaces of the lead-out end sectionare formed so as to be on the same plane. By using the coilin which the both end sections (lead-out end sectionsand) are formed on the same plane, the coil-embedded dust core can be made smaller in size, and high inductance can be provided.
