PROBLEM TO BE SOLVED: To provide an accurate pressure-sensitive sensor having a wide dynamic range of a detection pressure and excellent detection sensitivity. SOLUTION: A plurality of circular recessed parts 1a are arrayed and formed in the matrix direction on a substrate 1, and a pair of spiral electrodes 2, 3 are provided respectively on the bottom surface of each circular recessed part 1a. Three circular recessed parts 1a aligned in the row direction are treated as one set, and the upper side of the three circular recessed parts 1a is covered by oblong conductive pressure-sensitive rubber 4 relative to each set, and upper and lower ends 4a, 4b of the conductive pressure-sensitive rubber 4 are bonded onto the substrate 1 by an adhesive 5, to thereby support the conductive pressure-sensitive rubber 4 on the substrate 1. Hereby, this pressure-sensitive sensor 10, having the circular recessed part 1a, the pair of spiral electrodes 2, 3, and the conductive pressure-sensitive rubber 4 relative to each circular recessed part 1a, is formed.
