PROBLEM TO BE SOLVED: To provide an external stimulus detection system capable of reducing the amount of wiring for connecting a conductive fiber to a measurement device. SOLUTION: An external stimulus detection system comprises a sheet-like sensor 1 composed by weaving the conductive fiber 13 into a fiber 12; and a pressure detection unit 2 for computing the size of an external stimulus applied to the sheet-like sensor 1. In the conductive fiber 13, a pressure-sensitive section 13b where impedance is changed by an external stimulus and a non-pressure-sensitive section 13a, with a prescribed impedance where the impedance is not changed by an external stimulus are formed. The pressure detection unit 2 supplies input waves from the edge of the conductive fiber 13, when detecting the external stimulus, measures reflected waves where the input waves are reflected in the conductive fiber 13, and computes the impedance of the pressure-sensitive section 13b, based on the reflected waves, thus measuring the size of the external stimulus at the pressure-sensitive section 13b.
