Problem to be solved: to effectively prevent the propagation of bacteria and mold on the surface of the drain port around the entrance formed by the drain and the outer end of the water receiving body having the drain port and the member used in the state where the outer end is abutted against the surface of the drain port Provision of drainage structure.At least the outer end 1 is formed of a resin containing a substance having antibacterial anti fungal action. Even if water stays in the entrance, the material having the antibacterial action eluted into the surface of the resin is dissolved, and the reproduction of the fungus can be effectively prevented not only on the surface of the outer end portion but also in the surface of the drain port around the entrance.Diagram【課題】排水口を有する受け水体と、この排水口の表面に外側端部が当接している状態で用いられる部材とを少なくとも備えてなる排水部構造であって、この排水口と外側端部とで形成される入隅周辺の排水口表面における菌およびカビの繁殖が有効に防止される排水部構造の提供。【解決手段】少なくとも外側端部1を、抗菌防カビ作用を有する物質を含んでなる樹脂により形成する。入隅に水が滞留したとしても、この溜まった水に樹脂の表面に溶出した抗菌作用を有する物質が溶け、外側端部の表面のみならず、入隅周辺の排水口表面においても菌の繁殖を有効に防止できる。【選択図】図2
