PROBLEM TO BE SOLVED: To provide a fluid conduit for an endoscope capable of securing the flow rate by reducing the resistance of the fluid flowing inside the conduit without upsizing a device when the conduit is disposed inside a light source device, etc. and without deteriorating the mechanical strength. SOLUTION: A connection conduit 32 as the fluid conduit for the endoscope consists of a tubular member 41 made of a tubular metal material forming a conduit 41A with a prescribed inner diameter and a tubular member 42 made of a tubular metal material forming a conduit 42A with almost the same inner diameter as that of the tubular member 41. The tubular members 41 and 42 are connected at right angles to form the fluid conduit in the L-shape. The tubular member 41 has a bent part 50 with the shape bent in the direction crossing the longitudinal axis of the tubular member at an end. The bent part 50 has a female screw part 41a formed to thread-engage the tubular member 42 in the direction without making a male screw part 42a of the tubular member 42 project inside the conduit.
