An endoscope includes: an internal conductor that is formed of a conductive material; an external conductor that is electrically insulated from the internal conductor and is formed of a conductive material that configures a part of an exterior; a holder that holds a first conductor that is electrically connected to the internal conductor and a second conductor that is electrically connected to the external conductor such that the first conductor and the second conductor are separated from each other by a space with a predetermined spatial distance; and a water-tightness holding member that holds water-tightness in the space.

Endoscope and discharge control unit

An endoscope includes: a plurality of wires each having a distal end connected to a bending portion of an insertion portion and a proximal end extending into an operation portion; one or more tubular members provided on the operation portion and including a first part extending in a direction of a longitudinal axis of the insertion portion, a second part provided on a proximal end side of the first part and extending in a side direction to the longitudinal axis, and a bent part connecting the first part and the second part, any one of the plurality of wires being inserted into the one or more tubular members, the first part and the second part being fixed to the operation portion; and a stopper fixed in the operation portion and arranged to prevent movement of the bent part by abutting on an inside of bending of the bent part.
