<P>PROBLEM TO BE SOLVED: To provide a reactor with improved heat dissipation. <P>SOLUTION: A reactor 100 includes a coil wounded around a magnetic material core. The coil 10 of the reactor 100 is covered with a resin 31 except for a part of side surfaces (outer peripheral surface of the coil). Moreover, in the reactor 100, a metal heat-sink 33 covering the exposed portion of the coil 10 from the resin is attached on the resin. Between the coil 10 and the rear surface of the heat sink 33, a gel or curable heat-transmission material 32 in contact with both of them is disposed. The heat-transmission material 32 penetrates between the windings of the coil well, and transmits heat of the coil 10 to the heat sink 33 well. <P>COPYRIGHT: (C)2013,JPO&INPIT |
