PROBLEM TO BE SOLVED: To provide a pressure-sensitive sensor, having linearity for the pressure sensitivity of an output, and to improve an output stability and an output variation of the pressure sensitive sensor at a wide range, extending from a low temperature (-20°C or -40°C) to a high temperature (85°C). SOLUTION: The pressure-sensitive sensor comprises a resistance change type pressure sensitive sensor between electrodes 10, 20 of a pressure-applying side and a pressure receiving side by making a contact area mutually of the conductive painted films, formed from a pressure-sensitive conductive ink 13 added with conductive carbon black. The pressure-sensitive conductive ink 13 has the strength enhanced as resin and enhanced effect of the dispersion of the conductive carbon black, by adding 30 to 70 parts by weight of silicon dioxide to 100 parts by weight of silicone elastomer component as a binder.
