An object is to provide an applicator for medical-use liquids in which an appropriate amount of medical-use liquid such as disinfection liquid uniformly exudes from an application pad, the applicator being able to accurately apply a predetermined amount of medical-use liquid. An applicator for medical-use liquids includes: a handle section comprising a hollow cylindrical member, a liquid container incorporated in the cylindrical member, and a cleaving means of the liquid container； and an applying section comprising an attachment plate 10 of an application pad (integrally) fixed to a lower end of the cylindrical member to be an inclined cross section and the application pad fixed to the attachment plate. The attachment plate 10 is provided with a bank section 12 formed thick at a peripheral edge, a base bottom section 13 formed as a recess in a center, an inclined outflow hole 14 opened inclinedly with respect to the base bottom section near the base bottom section center such that the solution flows out toward an attachment plate distal end direction, and a weir 15 provided in an arcuate shape or a crescent shape. A flow of the solution flowed out from the inclined outflow hole is reversed to flow backward by the weir 15. An amount of liquid permeated into the application pad is adjusted.本發明的課題為提供一種醫療用液體施用器，係從塗佈墊均勻滲出適量的消毒液等醫療用液體，可正確塗佈預定量。本發明的醫療用液體施用器具有把手部及塗佈部，其中該把手部具備中空的筒狀構件、內裝於該筒狀構件的液體容器、及該液體容器的開裂機構；該塗佈部具備：塗佈墊的安裝板，係(一體)固裝於前述筒狀構件的下端而形成傾斜斷面；及附著於該安裝板的塗佈墊；於安裝板設有：堤台部，係厚壁地形成周緣；基底部，其中央形成凹部；傾斜流出孔，係對於基底部傾斜開口，以使前述液體在基底部中央附近朝向安裝板前端方向流出；及堰牆，係設置成圓弧狀或新月狀。從傾斜流出孔流出的液體的液流由於堰牆而反轉逆流，藉此調整液體對塗佈墊的滲透量。
