Abstract
An angular acceleration detection device includes a rotating weight, a fixed portion, a support beam, and a detection portion. The rotating weight is rotatable about a Z-axis with respect to the fixed portion by action of an inertial force generated by an angular acceleration about the Z-axis. The fixed portion is disposed at a position spaced from the rotating weight. The support beam is disposed in an X-Y plane between the fixed portion and the rotating weight, the support beam elastically supporting the rotating weight with respect to the fixed portion. The detection portion outputs a detection signal corresponding to stress generated in the support beam. A gravity center position of the rotating weight is aligned with the support beam when viewed in a Z-axis direction.
