A mirror control device includes a pivotally supported mirror (230), electrodes (340a-340d) spaced apart from the mirror (230), a driving voltage generation means (401) for generating a driving voltage corresponding to the desired tilt angle of the mirror (230) for each electrode, a bias voltage generation means (402) for generating, as a bias voltage for each electrode, a voltage which causes the tilt angle of the mirror (230) to have the same predetermined value upon being independently applied to each of the electrodes (340a-340d), and an electrode voltage applying means (403) for adding, for each electrode, the bias voltage to the driving voltage and applying the voltage after addition to a corresponding one of the electrodes (340a-340d).
