Abstract
The flush toilet has a waste receipt surface section (10) of a bowl section (1) formed continuously integrally with an inner rim wall surface section (15) of the rim portion disposed at a peripheral edge of an upper opening (13) of the bowl section (1) as a curved surface; and the inner rim wall surface section (15) of the rim portion acts as a flush water passage (16) of the bowl section. The flush water passage (16) of the bowl section is further configured such that the inner rim wall surface section (15) of the rim portion is shaped in an overhanging form inclining so as to hang over inside of the bowl section (1). The flush toilet of this configuration can be cleaned with ease and kept clean in sanitation.
