Abstract

The purpose of the present invention is to provide an inertial force detection device that can more accurately detect faults in a temperature sensor. Provided is an inertial force detection device configured so that in a state where an oscillating body is made to oscillate in a first direction, the amount of displacement when the oscillating body is displaced in a second direction due to the generation of angular velocity is detected as angular velocity, wherein the inertial force detection device has a means for performing control so that the oscillating body enters a state of resonance in the first direction, a temperature detection means for detecting temperature, and a means for detecting faults in the temperature detection means, and outputs a plurality of signals, which indicate the fault detection results of the three means, continuously from a single signal wire.
