PROBLEM TO BE SOLVED: To detect sliding and a sliding direction with a small, light, thin and wiring-saving configuration.SOLUTION: A sensor part 32 includes: electrode parts 33 arranged in a matrix and having electrodes 33A and 33B disposed away from each other with predetermined gaps therebetween; and a pressure-sensitive conductive sheet 34 disposed on the top surface of the electrode parts 33 and having a resistance value varying according to force Fin a normal direction. When a high-frequency waveform component generated by a sliding action on the sensor part 32 by a contact member 40 exceeds a predetermined threshold, initial sliding caused immediately before the occurrence of displacement of the sliding on the sensor part 32 by the contact member 40 is detected. At the same time, the direction of the sliding is detected from the direction of a center position of distribution of loads to the sensor part 32 at the time of detecting the initial sliding by calculating the center position of the distribution on the basis of change in the resistance value of the pressure-sensitive conductive sheet 34. |
