<p>PROBLEM TO BE SOLVED: To provide a compact reactor whose physical quantity in operation can be suitably measured.SOLUTION: A reactor 1 includes a coil 2 which has a pair of coil elements 2a, 2b which are connected to each other, and a magnetic core 3 which has a pair of inner cores 31 arranged in the coil elements 2a, 2b respectively and an outer core part 32 connecting those inner core parts 31 to each other so as to form a closed magnetic path. Further, the reactor includes a heat sink (a bottom plate part 40) on which the coil 2 is placed, and a sensor 7 which measures a physical quantity of the reactor 1 in operation. The coil elements 2a, 2b are cylindrical bodies constituted by spirally coiling winding wires 2w, and have end face shapes including corner R parts 21 formed by rounding corner parts, and the coil elements 2a, 2b are arranged in parallel so as to have their axes in parallel. The sensor 7 is arranged in a trapezoidal space formed of the opposed corner R parts 21 of the coil elements 2a, 2b and the bottom plate part 40.</p> |
