Summary:PROBLEM TO BE SOLVED: To make an endoscope insertion part thin in diameter by improving the strength of a resin tube for sending air or sending water of an endoscope without increasing its tube thickness, and to make an observation light source high in luminance and an imaging element high in pixel by enhancing a heat conductivity in the longitudinal direction of the resin tube, thereby cooling cool the heat generation area of an endoscope tip part. SOLUTION: The endoscope is provided with: a washing nozzle which sends air or water toward an observation window provided at the tip of the endoscope insertion part; and the resin tube 51 connected to the flow channel of the washing nozzle. Within the thickness of the resin tube 51, a plurality of heat conductive wires 67 extending in the longitudinal direction of the resin tube 51 are included, and the respective heat conductive wires 67 are arranged side by side without crossing with each other.
