PROBLEM TO BE SOLVED: To provide a technology capable of inhibiting deterioration of the cooling efficiency of a reactor which is caused by a heat radiation sheet being elongated by heat expansion of a winding wire of a coil at the reactor with a cooler which includes the heat radiation sheet between the coil and the cooler.SOLUTION: A reactor 100 with a cooler which is disclosed by the specification includes: a cooler 4 which is disposed so as to face one side surface of a coil 2 wound around a core 3 in a winding radial direction; a heat radiation sheet sandwiched between the one side surface of the coil 2 and the cooler 4; and comb members 63 including sinking combs 63a, each of which is inserted between the winding wire 21 and the winding wire 21 of the coil 2. |
