PROBLEM TO BE SOLVED: To provide an LC filter which enables efficient cooling of an AC reactor and achieves downsizing and weight reduction of a housing storing an LC filter part.SOLUTION: An LC filter according to one embodiment of the invention includes: a first AC reactor having a first core part and a first coil part, the first AC reactor in which one terminal of the first coil part is connected with an AC power source; a second AC reactor having a second core part and a second coil part, the second AC reactor in which one terminal of the second coil part is connected with an electric power conversion part which converts AC voltage into DC voltage; a capacitor; a housing which stores the first AC reactor, the second AC reactor, and the capacitor; a cooling air introduction part which is provided on one surface of the housing and introduces cooling air; and a cooling air discharge part which is provided on the other surface of the housing which faces the one surface and discharges the cooling air so that the cooling air flows in a predetermined direction. The second AC reactor is disposed so that a second gap is provided between an outer peripheral part of the second coil part and the housing and an axial direction of the second coil part corresponds to a direction that the cooling air flows along the second gap. |
