Abstract
A cord switch is composed of a hollow tubular member having elasticity and insulating properties, and a plurality of electrode wires disposed opposite an inner side of the tubular member and spaced apart by elastic force of the tubular member. The plurality of electrode wires each include a conductor formed by stranding a plurality of metal wires together. All of the metal wires constituting the conductors are helically stranded together.
