  • the holding member 15 is screwed into the screwing portion 141 of the connection structure 14 and moves forward and backward along the central axis Ax with respect to the connection structure 14 by changing the screwing state. Therefore, the elastic member 13 can be appropriately compressed. That is, the difference in expansion rate or contraction rate between the exterior member 10 and the metal member 12 due to heat or chemical attack added during the reprocessing can be effectively absorbed by the elastic member 13.
  • the O-ring 121A and the elastic member 13 can sufficiently secure watertightness between the distal end portion 102 and the metal member 12.
  • the end surfaces 102A and 131A that come into contact with each other are orthogonal to the center axis Ax, and the center axis Ax is the center. It is a plane extending all around in the circumferential direction. For this reason, the shape of each of the end surfaces 102A and 131A can be simplified, the manufacture thereof can be facilitated, and the adhesion between the end surfaces 102A and 131A can be improved.
  • the elastic member 13 is made of a material having electrical insulation. For this reason, the insulating property of the metal member 12 functioning as the ground terminal can be sufficiently ensured.
  • the elastic member 13 is made of a material having chemical resistance. For this reason, it is possible to suppress the deterioration of the elastic member 13 during the reprocessing.
  • the pair of locking portions 121 ⁇ / b> B are mechanically attached to the endoscope observation device 4 by being locked to the endoscope observation device 4.
  • the metal member 12 has a function of mechanically connecting to the endoscope observation device 4 in addition to a function as a ground terminal. For this reason, the number of components can be reduced as compared with the case where a configuration for mechanically connecting to the endoscope observation device 4 is separately provided.
  • the present invention should not be limited only to the above-described embodiments.
  • the metal member 12 functions as a ground terminal.
  • the present invention is not limited to this, and a configuration that functions as a signal terminal may be employed.
  • the endoscope system 1 has both the function of generating an ultrasonic image and the function of generating an endoscope image.
  • the present invention is not limited to this.
  • a configuration having only a generating function may be employed. That is, a configuration in which the ultrasonic probe 61, the ultrasonic observation device 3, and the like are not provided may be adopted.
  • the endoscope system 1 is used in the industrial field, and may be an endoscope system for observing the inside of a subject such as a mechanical structure.
