The pressure sensitive sensor includes a sheet base, an application-side and a receiving-side electrode provided on the sheet base and conducting coatings provided on the electrodes. The conductive electrodes have pressure-sensitive conductive ink containing conductive carbon black. Resistance between the application-side electrode and the receiving-side electrode changes by a contact area between the conductive coatings on the electrodes. The pressure-sensitive conductive ink has an enhanced strength as a resin and an enhanced effect of 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. The pressure-sensitive sensor has output stability and linearity at temperatures in a wide range from -40° C. to 85° C.
