Abstract

The present invention provides a sanitary western-style flush toilet in which stains are hardly adhered to a rim, and as a result, a nasty smell and the like are hardly generated. A western-style toilet body comprises a bowl portion and an open rim. The open rim has a rim channel in the inside thereof. At the rear of the western-style toilet body, a washing device which is capable of spouting water is formed. The bowl portion is washed by the water which is spouted from the washing device. An inward surface of an inner side wall portion of the open rim is an identical surface to a bowl face of the bowl portion.
