PURPOSE:To enable constitution without using mercury and to attain miniaturization by detecting the position of a conductor from contact of electrodes and the conductor and determining the posture. CONSTITUTION:A first member 1 and second member 2 have pyramidal recesses. A structural body is produced by joining the first member 1 and the second member 2. The freely movable conductor ball 3 is put in the structural body consisting of the first member 1 and the second member 2 and the static position of the conductor ball 3 is changed by the posture of a moving body. The posture of the moving body is detected by detecting the position of the conductor ball 3. Eight sheets of the electrodes insulated from each other are joined to the inside surfaces of the pyramids and are respectively connected to wirings. The electrodes insulated from each other conduct via the conductor ball 3 by contact of the conductor ball 3 with the respective electrodes. The posture of the moving body is detected if the conducting electrodes are detected. |
