PROBLEM TO BE SOLVED: To provide a reactor satisfying both heat dissipation of a coil, and suppression of cracking of cast resin, and to provide a cast resin giving such a reactor.SOLUTION: A reactor 1 has a coil 10, a case 30 housing the coil 10, and cast resin 40 filling the case 30. The coil 10 is fixed to the bottom surface 31 of the case 30, integrally therewith. The cast resin 40 has a specific gravity of 1.85 g/cmor less, and thermal conductivity of 0.7 W/m K or less. |
