Abstract
The present invention provides a magnetic element in which iron loss-caused heat generation is restrained and which can be produced with a high productivity. The magnetic element has a magnetic body which allows a magnetic flux generated by a coil () to pass therethrough. The magnetic body is a combined body formed by combining two halves, of the magnetic body composed of the compression molded and injection molded bodies, obtained by bisection made in an axial direction of the coil with each other. A compression molded magnetic body () is disposed at a portion generating iron loss-caused heat to a high extent or a portion inferior in heat dissipation performance. An injection molded magnetic body () is disposed at a portion other than the portion where the compression molded magnetic body is disposed. The compression molded and injection molded magnetic bodies are combined with each other.
