Title:
PRESSURE SENSOR AND MANUFACTURING METHOD OF PRESSURE SENSOR
Document Type and Number:
Japanese Patent JP2018105816
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure sensor having plural electrode wires inside a hollow tubular member disposed parallel to the central axis of a tubular member the sensitivity of which does not reduce with respect to a pressure in a specific direction, and a manufacturing method of pressure sensor capable of desirably designing the length of a finished product without using any spacer.SOLUTION: The pressure sensor includes: a hollow tubular member 2 of an elastic insulator; and n electrode wires 3 which are held inside the tubular member 2 being separated from each other. When the tubular member 2 elastically deforms when subjected to a pressure from the outside, at least any of two electrode wires 3 in the n electrode wires 3 come into contact with each other. The n electrode wires 3 extend in a straight line parallel to the central axis of the tubular member 2.SELECTED DRAWING: Figure 1
