PROBLEM TO BE SOLVED: To make it difficult to collect urine by narrowly forming the upper surface of an upper plate part except the surface part opposed to a seat leg part. SOLUTION: The upper surface of an upper plate part 3 except the surface part opposed to a seat leg part is narrowly formed. Therefore, the seat leg part is surely placed on the opposed surface part 8 of the upper surface of the upper plate part 3, and urine or dirt is hardly collected in the narrow upper plate part 3. Since the upper side of a side plate part 5 is inclined outward, the urine fallen to the side plate part 5 is slid on this inclination and surely fallen into the bottom surface of a bowl part 1. Further, since the lower plate of a rim part 2 is protruded to the bowl 1, the splash of filthy water from the bottom surface of the bowl 1 can be prevented. Therefore, a man can urinate without caring about soiling of the upper surface of the upper plate part 3. Accordingly, the seat leg part can be surely placed on the opposed surface part of the upper plate upper surface, and it can be made difficult to collect urine or dirt in the narrow upper plate upper surface.
