<P>PROBLEM TO BE SOLVED: To provide a pressure-sensitive conductive sensor using a pressure-sensitive conductive material, enhancing resolution of pressure detection in a low-pressure range, and to provide a pressure calculation method. Ž<P>SOLUTION: The pressure-sensitive conductive sensor detects the minimum value of a peak voltage output from a pressure-sensitive conductive sensor part provided with a pressure-sensitive conductive material on an electrode (S501), by a click operation by a user. Then, the maximum value of the peak voltage is calculated (S502) based on the minimum value of the peak voltage and data of an upper limit characteristic curve of the pressure-sensitive conductive material stored in advance. Then, a change-over threshold value is calculated (S503) based on the minimum value and the maximum value. The change-over threshold value is compared with an output voltage from the pressure-sensitive conductive sensor part (S504), and any of F-R characteristic curves stored in advance is selected (S505), based on a comparison result. Finally, pressure is calculated from the output voltage output from the pressure-sensitive conductive sensor part (S506), based on the selected F-R characteristic curve.
