PROBLEM TO BE SOLVED: To provide a sensor for measuring pressure distribution and frictional force distribution, having a relatively simple structure, easy to miniaturize, and able to be made up of flexible materials if necessary. SOLUTION: This sensor is equipped with a pair of pressure plates 1, 2 having a large number of projections and recesses shaped so as to fit to each other on their mutually opposed surfaces, and a sheet-like pressure-sensing conductive material 3 put between the mutually opposed surfaces of the pressure plates. Detection parts A to D are formed by disposing electrodes A1 to D1 and electrodes A2 to D2 opposed thereto, respectively, on top faces 11, bottom faces 12, and intermediate faces, of the projections or recesses on the mutually opposed surfaces of the pressure plates. A processing circuit is provided for detecting electric conductivity between the electrodes of each detection part. Based on the detected electric conductivity, the distribution of pressure vertically acting on a sensor surface and the distribution of frictional force acting parallel to the sensor surface of an outside surface of the pressure plate can respectively be measured.
