Abstract: A water passage in a front region of a bowl of a toilet includes an upstream side water passage and a downstream side water passage formed on the upstream side and on the downstream side, respectively, of a front end of the bowl surface. The curvature radius of the downstream side water passage in a plan view is set to be smaller than the curvature radius of the upstream side water passage in a plan view. The water passage in the front region of the bowl has a flow path vertical cross-section that is taken in the vertical direction and is formed between a shelf surface and an overhanging part. The cross-sectional area of the flow path vertical cross-section taken in the vertical direction is set to be the smallest in a front end of the water passage.

Abstract: The water conduit has: a first water-guiding portion extending from a water supply portion, where the flush water is supplied to the water conduit, to a first spout port located on one of right and left sides of the bowl portion; and a second water-guiding portion extending from the water supply portion to a second spout port located on the other side. The water supply portion is located at a position on the one side. The flush water is supplied to the water supply portion in a direction from the water supply portion toward the first water-guiding portion. A collision wall is provided on a way of the first water-guiding portion such that at least a part of the supplied flush water collides with the collision wall. The at least part of the flush water having collided with the collision wall is supplied to the second water-guiding portion.

Abstract: Disclosed is a process for producing a sanitary ware. The sanitary ware includes a glaze layer and a photocatalyst layer provided on the glaze layer. The photocatalyst layer is an oxide film including a co-fired product of a precursor of titanium oxide and a precursor of zirconium oxide and contains 65 to 85% by mass of titanium oxide and 15 to 35% by mass of zirconium oxide. The process includes the steps of applying a solution containing at least a precursor of titanium oxide and a precursor of zirconium oxide on a surface of a sanitary ware free from a photocalyst layer, and then firing the coating to form a photocatalyst layer.
