Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a urea water supply pipe capable of thawing urea water frozen in a pipe body in a short time by effectively heating the frozen urea water by engine cooling water on a cooling water pipe side, excellent in weatherability, and durable for continuous use for a long time. SOLUTION: The urea water supply pipe 14 is constituted by arranging the cooling water pipe 10 guiding the engine cooling water 11 heated through an engine along the pipe body 7 for guiding the urea water 6 to a selective reduction type catalyst as a reducing agent. The pipe body 7 and the cooling water pipe 10 are formed to have semicircular cross sections by an anticorrosive metal pipe, and back surfaces 7a and 10a forming flat surfaces respectively are closely jointed back to back.
