Abstract

PURPOSE:To improve heat transmission property and magnetic efficiency by the coil bobbin largely by molding the coil bobbin with a resin material into which metal powder is mixed. CONSTITUTION:The coil bobbin 6 is arranged to the outer circumference of a packless pipe 1, the circumference of the bobbin 6 is surrounded by a coil 7, and an electromagnetic device is formed. The bobbin 6 is molded with the resin material into which the metal powder is mixed at that time. When the coil 7 is conducted and eddy currents are generated at the coil 7, Joule heat is generated, and the heat is transmitted excellently to a magnetic transmitting case 8, the packless pipe 1 and a main body 2 through soft iron group metal powder having superior heat transmission property contained in the bobbin 6. Accordingly, coil 7 itself can be miniaturized.
