A gyro sensor includes a first register that stores angular velocity information; a second register that stores sensitivity deviation information of the angular velocity information stored in the first register; a serial communication circuit; and a control circuit that selects the first register or the second register in accordance with designation information supplied through the serial communication circuit. When the first register is selected by the control circuit, the angular velocity information stored in the first register is output through the serial communication circuit, and when the second register is selected by the control circuit, the sensitivity deviation information stored in the second register is output through the serial communication circuit.
