PROBLEM TO BE SOLVED: To provide a pressure sensor for an endoscope scope capable of detecting a force applied to a tip of the endoscope scope with high sensitivity, and an endoscope scope having the pressure sensor.SOLUTION: A pressure sensor 20A comprises: an annular pressure sensitive part 27 consisting of a first electrode 25 formed in an annular shape, and a pressure-sensitive member 26; and a plurality of second electrodes formed on a surface of the pressure sensitive part 27 in a direction crossing an extension direction of the first electrode 25. The pressure sensitive part 27 is fixed to an outer peripheral side of an end part at a tip side of a cylindrical hood 31. The rigidity of the cylindrical hood 31 is larger than the rigidity of the pressure sensitive part 27, and is equal to or smaller than the rigidity of an endoscope scope. The pressure sensor 20A can be used by being attached to an outer peripheral side of a tip of an insertion part of the endoscope scope.SELECTED DRAWING: Figure 5 |
