PROBLEM TO BE SOLVED: To provide a piping structure for sprinkler of making it possible to dealing with flexibly for setting a sprinkler head. SOLUTION: A piping for sprinkler is composed of a water supply pipe part 1 and a branch pipe part 11 that is branched from the water supply pipe part 1 with looping to form a no-end channel. The branch pipe part 11 is composed of multiple junction pipe parts 12, which are arranged in succession, and a joint 13, which connects with adjacent junction pipe part 12 and is mounted with a sprinkler head 13a. The junction pipe part 12 is made of resin pipe that has flexibility. The junction pipe part 12 is fixed to the joint 13 and the water supply pipe part 1 using a mechanical joint and the like, without axial rotation of junction pipe part 12.
