An endoscope guide tube includes a tube member to be inserted into a device including a live part, the tube member being constructed by including a tube body made of an insulating member that makes up an outer layer and a braid that makes up an inner layer of the tube body and braids, into a tubular form, metal members wound, for example, clockwise with a plural number of carriers including a predetermined number of ends in parallel and insulating members wound with a plural number of carriers including a predetermined number of ends in a direction opposite to a winding direction of the metal members in parallel, a connection member provided with a first contact connecting in a bundled manner ends of the metal members in substantially half the carriers in number of the plural metal members making up the tube member and a second contact connecting in a bundled manner ends of the metal members with the remaining carriers in number of the plural metal members, at least one of a first contact side conduction detection section that detects that the live part contacts the metal members connected to the first contact and a second contact side conduction detection section that detects that the live part contacts the metal members connected to the second contact, and a signal output section that outputs a notification signal notifying that the metal members of the tube member are exposed to a notification section.
