Abstract: Provided is a power converter that allows a reduction in EMC noise current flowing through a control circuit board. A power converter 1 includes a semiconductor module 52, a capacitor 51, a control circuit board 45a, positive and negative-side bus bars 41, 42 connecting the semiconductor module 52 and the capacitor 51, a base 33 electrically connected to a ground of the control circuit board 45a, the control circuit board 45a being placed on the base 33, and an electrical conductor 35 electrically connected to the base 33 and extending in a stacking direction in which the base 33 and the control circuit board 45a are stacked. The positive and negative-side bus bars 41, 42 extend around the electrical conductor 35 and are connected to the semiconductor module 52.
