摘要： A calibration method for an inertial drive actuator of detecting a position of a moving body based on an electrostatic capacitance is proposed. The calibration method includes driving the moving body; outputting a first signal for detecting the electrostatic capacitance of opposing parts of a moving body side electrode provided on the moving body and a detecting electrode provided opposing the moving body side electrode; receiving a second signal obtained after the first signal output at the outputting has passed through the moving body side electrode and the detecting electrode; and calculating an optimum first signal based on the second signal received at the receiving.
