PURPOSE: To enable attainment of mass production by a common structure and also to reduce the cost by a method wherein acceleration detecting elements of minute structures each of which can detect acceleration in a single-axis direction are formed to have the common structure, by using a micromachining technique, as an acceleration detector which can detect the acceleration of a moving body in a multi-axis direction, and the elements are fitted to a circuit board through a connector having fitting surfaces being vertical to the directions of the discrete axes being perpendicular to one another so that the acceleration detector be formed.
CONSTITUTION: In the acceleration detector 1, three acceleration detecting elements 2 of minute structures are connected to a circuit board 4 through a connector 3 having fitting surfaces being vertical to the directions of three axes intersecting one another perpendicularly. The circuit board 4 is provided with a processing circuit 5 which amplifies a detected electric signal, converts it into a pulse signal and takes out an acceleration signal, and these components are molded in a case 6 by a potting material 8.
