PROBLEM TO BE SOLVED: To provide a chemical liquid applicator and a chemical liquid application tool capable of avoiding insufficient supply of a chemical liquid and reducing a stimulus to a coated part.SOLUTION: A chemical liquid applicator (1) comprises a container (10), and a chemical liquid application tool (20) capable of switching between a state where the inside of the container (10) is sealed and a state where a chemical liquid can be applied to the outside of the container (10). The chemical liquid application tool (20) has a substrate (30) having an outflow port, and a valve body (40) capable of closing the outflow port and making the chemical liquid flow out through the outflow port. The substrate (30) comprises a coated surface (34) including a defining edge part (35), for applying the chemical liquid, and a retaining part (36). The valve body (40) comprises a closing part (44), a biasing part (46), and a projection part (48). The coated surface (34) has a shape curved so as to project in an action direction of a biasing force.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】薬液の供給不足の回避と被塗布部に対する刺激の低減とを両立可能な薬液塗布器具及び薬液塗布具を提供すること。【解決手段】薬液塗布器具(1)であって、容器(10)と、容器(10)内が密閉された状態と薬液を容器(10)外に塗布可能な状態とを切り替え可能な薬液塗布具(20)と、を備え、薬液塗布具(20)は、流出口を有する基体(30)と、流出口を閉塞すること及び流出口を介して薬液を流出させることが可能な弁体(40)と、を有し、基体(30)は、画定縁部(35)を含みかつ薬液を塗布するための塗布面(34)と、抜止部(36)と、を有し、弁体(40)は、閉塞部(44)と、付勢部(46)と、突出部(48)と、を有し、塗布面(34)は、付勢力の作用方向に凸となるように湾曲する形状を有すること。【選択図】図2
