1. An inertial force sensor comprising:

  • an oscillator and a sensory circuit for outputting an angular velocity signal after smoothing a detected signal outputted by the oscillator;

    whereinthe sensory circuit has a low-pass filter and a high-pass filter formed by connecting a resistor and a capacitor;

    one end of the capacitor of the high-pass filter is connected to between the resistor and the capacitor of the low-pass filter;

    an angular velocity signal is outputted after smoothing the detected signal through the low-pass filter and the high-pass filer; and

    a switch is connected in parallel with the resistor of either one of the low-pass filter and the high-pass filter, and the capacitor is charged by making the switch on.
