Abstract

A pressure-sensitive sensor includes a long hollow insulation that is elastically deformable and includes a hollow portion extending continuously in a longitudinal direction, a plurality of electrode wires that are provided along the inner peripheral surface of the hollow portion throughout the longitudinal length and are arranged facing each other with a distance therebetween so as to come into contact with each other when bent with elastic deformation of the hollow insulation, each electrode wire being formed by providing a conductive cover around a conductor, and an outer layer formed to cover an outer surface of the hollow insulation. The hollow insulation includes an insulating composition (A) including a styrene-based thermoplastic elastomer (a1). The outer layer including an insulating composition (C) including a thermoplastic polyurethane (c1) and an acid-modified polymer (c2) that is modified with an unsaturated carboxylic acid or a derivative thereof.
