A motor including electrical components laid out to avoid enlargement of the motor. The motor includes a rotor, a cylindrical housing including a closed end and an open end and accommodating the rotor, and an end bracket fixed to the housing to close the open end and including a connector support. Two power supply terminals extend to the connector support. A noise prevention element includes a connection terminal connected to the power supply terminals. A rotation detector detects rotation of the rotor and includes a detector body. The noise prevention element is arranged between the two power supply terminals. The detector body and the noise prevention element are arranged at a portion of the end bracket closer to the connector support and aligned in an axial direction of the motor.
