PROBLEM TO BE SOLVED: To provide a reactor which achieves excellent heat radiation performance.SOLUTION: A reactor 1A includes: a coil 2 formed by winding a winding wire; and a magnetic core 3 in which the coil 2 is disposed, the magnetic 3 forming a closed magnetic path. The magnetic core 3 includes: inner core parts 31 disposed at the inner side of the coil 2; and heat radiation sheets 4, each of which is disposed in at least a part of a space between an inner peripheral surface of the coil 2 and an outer peripheral surface of the inner core part 31 which faces the inner peripheral surface of the coil 2. The heat radiation sheet 4 contacts with the coil 2 and the inner core part 31. |
