An acceleration detection device is provided which is capable of detecting accelerations in two or more directions. The base end of a beam is fixed to a support section on a board. A weight is provided in the front end of the beam which is formed so as to extend horizontally along the board surface with a gap with it and the surface of the board. The position of the center of gravity G of the weight is set at a position spaced perpendicularly apart from the center axis of the beam in order that the inertial moment acts when an acceleration along the length (in the X direction) of the beam is applied. The front end surface of the weight is formed into an upright surface of a movable electrode, and a fixed electrode is formed at a position facing the movable electrode with a gap therebetween. When an acceleration in the X or Y direction is applied, the beam is flexed upwardly or downwardly in proportion to the magnitude of the acceleration, causing the weight to be inclined upwardly or downwardly while being displaced upwardly or downwardly. Thus, the electrostatic capacity between the movable electrode and the fixed electrode increases or decreases. The magnitude of the acceleration can be detected on the basis of the amount of such change of the electrostatic capacity.
