A bus bar device with a noise filter includes a magnetic body, a bus bar and first to third capacitors. The bus bar has input and output ends and extends through the magnetic body. The capacitors are disposed on an electrical path between the bus bar and a ground conductor surface. The first capacitor is located at the input end side of the bus bar and the second and third capacitors are located at the output end side. The first capacitor has one end connected to the bus bar and the other end connected to the ground conductor surface in one of two regions divided by the bus bar. Each one of the second and third capacitors has one end connected to the bus bar and the other end connected to the ground conductor surface in the same region as the first capacitor or in the other region.
