A terminal structure of an in-vehicle motor is provided with a motor main body including a motor terminal (28) connected to a coil section, and a circuit main body (5) assembled to the motor main body by holding a circuit board (18) which controls rotation of the motor main body. A stress relaxing section (35) is arranged at the middle section of an intermediate conductor (34) to reduce stress operating to the intermediate conductor (34) connecting the motor terminal (28) and the circuit board (18) and improve conduction reliability of an electrically connecting section.
