A vibration type inertial sensor comprises: two dead weights (2, 3); means (C1, C2, C3, C4, +vd, -vd) for displacing the two dead weights in the anti-phase; two sets of electrodes (C5, C6, C7, C8) for detecting, as capacitance changes, the displacements of the two dead weights; and a C/V converting unit (53) for converting the capacitance changes of the electrodes to electric signals. In the vibration type inertial sensor, a set of electrodes (e.g., C5 and C8), which exhibit an increased electrostatic capacitance therebetween in the case where the two dead weights (2, 3) are displaced in the anti-phase, are electrically connected to each other, and a set of electrodes (e.g., C6 and C7), which exhibit a reduced electrostatic capacitance therebetween in the foregoing case, are electrically connected to each other, and further these sets of electrodes are connected to the C/V converting unit (53).",
