SOLUTION: The urine bag has the chamber comprising a main body and a lid body, and the lid body is equipped with the backflow prevention valve at a connection opening in the lower part. The backflow prevention valve is connected to the connection opening with a boat-shaped cross section, and the backflow prevention valve 5 with both welded (5c) ends of two sheets 5a, 5b is connected to the end part of the boat-shaped part 7a. The connection is realized by inserting the backflow prevention valve 5 into the boat-shaped part 7a, or a urine inlet 7, provided in the lower part of the lid body 2 of the chamber and welding the backflow prevention valve 5. One end of the holding hanger is opened, and the end part is made of both upper and lower parts opposing mutually and has a hook mechanism.
