PROBLEM TO BE SOLVED: To provide a welding torch that further reduces the disturbance of a shield gas made to flow out from a nozzle tip toward a welding part. SOLUTION: The welding torch 100A is provided with a torch body 200 having a fixed axial length, a nozzle 310 provided at the tip of the torch body 200, and a shield gas supply path formed inside the torch body 200. The welding torch is composed so as to feed the shield gas to the nozzle 310 through the shield gas supply path. The shield gas is introduced into the shield gas supply path through a first throttle part (A) provided at the base end side of the shield gas supply path, and the shield gas in the shield gas supply path is fed into the nozzle through a second throttle part (B) provided at the tip side of the shield gas supply path.
