Pressure-sensitive sensor and method of manufacturing the same

Abstract

An assembly workability of a pressure-sensitive sensor is improved. The pressure-sensitive sensor includes: a hollow outer cover; first to fourth conductive wires which are provided inside the outer cover and are electrically connected to each other in response to elastic deformation of the outer cover; and a conductive wire intertwined portion which is provided at one side of the outer cover in a longitudinal direction and is formed by bringing the second and fourth conductive wires into contact with each other. Thereby, a short-circuit wire for electrically connecting the second and fourth conductive wires can be eliminated, and a welding work for connecting the short-circuit wire can be eliminated. Thus, the assembly workability of the pressure-sensitive sensor can be improved. The number of portions to be welded can be reduced, thereby suppressing occurrence of welding failure or the like.
