An acceleration detector comprising a rotor rotatably supported within a housing and rotating against the urging force of a torsion spring based on acceleration, a pair of contact terminals contacting each other to be in an electrically connected state by rotation of the rotor at an inner end portion provided within the housing, and a supporting portion integrally formed with the rotor and supporting the torsion spring. The supporting portion is displaced by a predetermined amount in a predetermined direction from the rotary center of the rotor so that the spring effect center when torque is exerted on the torsion spring by rotation of the rotor substantially corresponds to the rotary center of the rotor. This construction of the acceleration detector produces the desired performance approximating the design value in an acceleration detector.
