ABSTRACT:
On the upper surface of a flexible substrate, four displacement electrodes are arranged. A fixed substrate is arranged thereabove, and fixed electrodes opposite to the displacement electrodes are respectively arranged on the fixed substrate. These displacement electrodes and the fixed electrodes form capacitance elements C1 to C4, respectively. A columnar working body is fixed on the lower surface of the flexible substrate. A bending is produced in the flexible substrate on the basis of an acceleration exerted thereon. As a result, capacitance values of the respective capacitance elements C1 to C4 vary. The capacitance values of the capacitance elements C1 to C4 are converted to respective voltage values V1 to V4. A component in the X-axis direction is obtained as Vx=(V1+V4)-(V2+V3), a component in the Y-axis direction is obtained as Vy=(V1+V2)-(V3+V4), and a component in the Z-axis direction is obtained as Vz=V1+V2+V+V4.
