PROBLEM TO BE SOLVED: To provide a technology that inhibits tearing of an end part of a heat transfer sheet sandwiched between a coil and a cooling member.SOLUTION: A reactor 2 includes a resin cover 10 which covers a coil 4 excluding a lower surface 4b of the coil 4. The resin cover 10 has side wall parts 12, each of which is provided along a lateral surface 4c erected from the lower surface 4b of the coil 4. A groove which opens so as to face a case 30 is formed between each corner part 4k of the coil 4 and a lower end 12a of the side wall part 12. Protrusions 33 facing the grooves are provided at the case 30. Each side end part of a heat transfer sheet 20, which extends in a coil winding axis direction, is sandwiched between the groove and the protrusion 33.SELECTED DRAWING: Figure 3 |
