A rotation detection device includes a rotation detection circuit (74), a step-up power supply circuit (71), a step-down power supply circuit (73), a first power supply path (L1), and a second power supply path (L2). The rotation detection circuit is configured to detect a rotation number of a motor that generates a torque applied to a steering mechanism of a vehicle, based on an electric signal. The electric signal is generated according to a rotation angle of the motor that is acquired through an in-vehicle sensor (53).
