PROBLEM TO BE SOLVED: To provide a synthetic resin U-shaped groove for inexpensively manufacturing the synthetic resin U-shaped groove, by easily connecting the mutual synthetic resin U-shaped grooves, in the synthetic resin U-shaped groove having a smooth inner wall surface and an outer wall surface formed in a waveform. SOLUTION: This synthetic resin U-shaped groove 10 is formed by integrally molding an outer wall material 30 composed of a corrugated plate and having a cross section forming a substantially U shape, on the outside surface side of an inner wall material 20 composed of a plate and having a cross section forming a substantially U shape. The synthetic resin U-shaped groove 10 is characterized in that one end part is formed in a connecting part X for projecting an end part of the outer wall material 30 from an end part of the inner wall material 20, and the other end part of the synthetic resin U-shaped groove 10 to be connected, is fittably formed inside the exposed outer wall material end part of the connecting part X.
