Abstract
A pressure-sensitive sensor, includes a hollow tubular member including an elastic insulating material; and n electrode wires (n being an integer of not less than 3) arranged away from one another and held inside the tubular member, wherein when an external pressure is applied to the tubular member, the tubular member elastically deforms such that at least two of the n electrode wires contact with each other, and wherein the n electrode wires extend linearly and parallel to a central axis of the tubular member.
