In this case, after the bowl portion 1 is molded with a synthetic resin material as a base, the region F1 is subjected to plasma treatment to develop hydrophilicity on the resin surface. Ar, N 2 , O 2, or a mixed gas thereof can be appropriately used for the plasma treatment.
　撥水面７は、微細な凹凸形状によって得ることが可能である。この場合、ボウル部１をベースとなる合成樹脂材料で成形した後に、領域Ｆ２に、たとえば図５Ａ、図５Ｂに示すような微細な凹凸形状を形成することで、樹脂表面に撥水性を発現させ、領域Ｆ２の撥水性を向上させる。 The water repellent surface 7 can be obtained by a fine uneven shape. In this case, after forming the bowl portion 1 with a synthetic resin material as a base, the region F2 is formed with a fine concavo-convex shape as shown in FIGS. 5A and 5B, for example, so that the resin surface exhibits water repellency. The water repellency of the region F2 is improved.

　第１０の形態の小便器では、第１～第５のいずれか一つの形態の小便器において、内面（１０）は親水面（６）と撥水面（７）を含み、親水面（６）は、親水性の添加剤が混入された合成樹脂製の面であり、撥水面（７）は、撥水性の添加剤が混入された合成樹脂製の面である。 In the urinal of the tenth aspect, in the urinal of any one of the first to fifth aspects, the inner surface (10) includes a hydrophilic surface (6) and a water repellent surface (7), and the hydrophilic surface (6) The surface made of a synthetic resin mixed with a hydrophilic additive, and the water repellent surface (7) is a surface made of a synthetic resin mixed with a water repellent additive.
　したがって、第１０の形態の小便器では、親水性の添加物が混入された合成樹脂材料と、撥水性の添加剤が混入された合成樹脂材料を用いて、ボウル部（１）を成形することで、親水面（６）と撥水面（７）を形成することができる。 Therefore, in the urinal of the tenth embodiment, the bowl portion (1) is formed using a synthetic resin material mixed with a hydrophilic additive and a synthetic resin material mixed with a water-repellent additive. Thus, the hydrophilic surface (6) and the water repellent surface (7) can be formed.
　なお、合成樹脂製のボウル部を備える小便器は前記の各形態に限定されず、適宜の設計変更を行うことや、公知の技術を適宜組み合わせることが可能である。 In addition, the urinal provided with the synthetic resin bowl portion is not limited to each of the above-described forms, and appropriate design changes can be made or known techniques can be appropriately combined.
