Abstract
A pressure-sensitive sensor includes a hollow tubular member including an elastic insulation, plural electrode wires spaced from one another and held on an inner circumferential surface of the tubular member, and helical ribs formed on at least one of inner and outer circumferential surfaces of the tubular member along a longitudinal direction thereof. The electrode wires are helically arranged along the longitudinal direction. A helical direction of the helical ribs of the tubular member is a same as a helical direction of the helically-arranged electrode wires.
