Provided is a power converter which is applied to a power converter equipped with a switching element provided on a line, and a radiator connected to a predetermined potential such as a ground potential. The power converter reduces noise which is caused by a parasitic capacitance generated between the switching element and the radiator and which is output to an input side of the power converter, and the power converter has durability against vibration. A noise eliminator 11 in which a conductive member is covered with insulator is provided between the switching element (semiconductor switch SW) and the radiator (heatsink HS). A flexible connecting line 11c connected to a conductive member 11a of the noise eliminator 11 is connected to an on-board line B1 disposed on a circuit board B.
