Patent ID: 8801603

Claim:
An endoscope comprising: a distal end rigid member made of resin and including a communicating hole for an insertion channel; a channel tube connecting member formed in a tubular shape using a member having conductivity, the channel tube connecting member having a distal end side fitted and fixed in the communicating hole of the distal end rigid member and a rear end side connected to an insertion channel tube; a bending piece member formed in a tubular shape using a member having conductivity, the bending piece member being fixed to just behind a rear end side of the distal end rigid member with the channel tube connecting member being housed inside the bending piece member; and a protruding portion provided on a circumferential surface of one of the channel tube connecting member and the bending piece member and configured to elastically protrude toward a circumferential surface of the other of the channel tube connecting member and the bending piece member, the protruding portion contacting the circumferential surface of the other of the channel tube connecting member and the bending piece member to establish conduction when the bending piece member is fixed to the distal end rigid member with the channel tube connecting member being housed inside of the bending piece member; wherein the protruding portion is provided on an inner circumferential surface of the bending piece member, and the channel tube connecting member includes a stepped portion provided on a part of an outer circumferential surface in a longitudinal direction, and when the bending piece member is fixed to the distal end rigid member with the channel tube connecting member being housed inside of the bending piece member, a distal end of the protruding portion contacts the stepped portion to establish conduction.
