<P>PROBLEM TO BE SOLVED: To provide a reactor exhibiting excellent heat dissipation. <P>SOLUTION: A reactor 1 comprises a core 3 composed of a magnetic powder mixed resin produced by dispersive mixing of magnetic powder to resin, and a coil 2 buried in the core 3. In a section perpendicular to the direction of the winding axis, as shown on fig. 2, at least one of the inner shape and outer shape of the coil 2 has an uneven shape. Preferably, the coil 2 is formed by spirally winding a rectangular wire having a substantially rectangular section perpendicular to the longitudinal direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
