Abstract
Provided is an electric power steering device including: a DC power supply; a motor; an inverter circuit configured to convert a DC power output from the DC power supply to an AC power and output the AC power after the conversion to the motor; and a filter circuit, which is provided between the DC power supply and the inverter circuit, and includes a choke coil. The choke coil includes: a core; and one or more conductor sets each including two conductors wound in parallel on the core. A tip on one side of each of the two conductors included in each of the conductor sets is connected to the DC power supply side, and a tip on another side of each of the two conductors is connected to the inverter circuit side.
