PROBLEM TO BE SOLVED: To provide an accurate external factor load position specification/detection method.SOLUTION: A pressurization sensor P is constituted by twisting two core wires 1, 1a together via an interposition 5, and performing resin coating 7 of an outer peripheral surface of the twisted core wires via press winding 6. When both core wires 1, 1a are trodden on and conductors 2, 2 are conducted, a fact that both core wires 1, 1a are trodden on is notified with conduction signals of the conductors 2, 2. Resistances R, Rbetween one end and the other end of both core wires via a conductor conduction part D are simultaneously measured. The entire length of both core wires is considered as L, electric resistances of the entire length of both core wires are considered as r, r, distance from one end of the core wires at a conducted part is considered as L, the distance Lis calculated from L×1/2×(R-R+r+r)/(r+r) based on the measured values R, R, and a position (conducted part) where an external factor is generated is specified with a calculated value of the distance.
