Abstract:
1. An inertial force sensor comprising: a detecting device which detects an inertial force, wherein the detecting device includes: an X-axis, a Y-axis, and a Z-axis are orthogonal to each other, each end of said two second beams has at least one folding portion, the two first beams are arranged on a substantially identical straight line, a longitudinal direction of the two first beams are arranged in the Y-axis direction, a longitudinal direction of the two second beams are arranged in the X-axis direction, and each end of the two second beams are capable of being driven and oscillated in the Y-axis direction, such that: an angular velocity about the Z-axis is detected by detecting distortion of the detecting device in the X-axis direction, and an angular velocity about the X-axis is detected by detecting distortion of the detecting device in the Z-axis direction.
