PROBLEM TO BE SOLVED: To provide an air-feeding/liquid-feeding apparatus for endoscopes by which the preferable arrangements of an air-feeding conduit and a liquid-feeding conduit are attained, and specified durabilities of the air-feeding conduit and the liquid-feeding conduit can be ensured.SOLUTION: The air-feeding/liquid-feeding apparatus includes the air-feeding conduit 112 which communicates with an air-feeding tube, and the liquid-feeding conduit 114 which communicates with a liquid-feeding tube on the distal end section having an approximately cylindrical shape of the insertion section of the endoscope. In addition, a junction tube 110 including a junction section 115 which has made the air-feeding conduit 112 and the liquid-feeding conduit 114 unified is installed. The air-feeding conduit 112 and the liquid-feeding conduit 114 in the junction tube 110 have a bent shape. Also, the junction tube 110 has a structure wherein the central axis of the air-feeding conduit 112, the central axis of the liquid-feeding conduit 114, and the central axis of the junction section 115 are present on planes which are different from each other in the connected section with the air-feeding conduit 112 and the liquid-feeding conduit 114.
