PROBLEM TO BE SOLVED: To simplify configuration and at the same time improve accuracy. SOLUTION: Two magnetization bodies 21 and 22 are magnetized so that the side parts at the side of a variable impedance element 23 become different magnetic poles, thus generating a specific magnetic field. In the variable impedance element 23, impedance changes according to the change in magnetic field. When outer force is applied in x direction to a force detection sensor, the magnetization bodies 21 and 22 connected to a support stand 12 via a connection member 14 and a leaf spring 15 are displaced in x direction, the relative position relationship between the magnetization bodies 21 and 22 and the variable impedance element 23 changes and hence a magnetic field for the variable impedance element 23 changes and the impedance of the variable impedance element 23 changes. Therefore, by detecting a signal corresponding to the impedance of the variable impedance element 23, the level of the outer force can be obtained. |
