Abstract
Inertial force sensor includes detecting element that detects inertial force. Detecting element includes: two first orthogonal arms each having first arm and second arm that are connected to each other in a substantially orthogonal direction; support portion that supports two first arms; fixing arms; and weights. Second arms include: bent portions; facing portions that are bent at bent portions so as to face second arms; driving electrodes that are formed in two facing portions facing each other, and drive and vibrate facing portions; and detection electrodes that are formed in the other two facing portions facing each other, and detect the distortion of facing portions. According to this structure, it is possible to achieve small inertial force sensor capable of detecting a plurality of different inertial forces and inertial forces acting on a plurality of detection axes.
