PROBLEM TO BE SOLVED: To provide a volatilization apparatus capable of volatilizing a liquid medicine without waste.SOLUTION: A volatilization apparatus includes a container 2 storing a liquid medicine, a cylindrical body 41 having a lower end 41a positioned in the container and an upper end 41b opened to the upper part of the container, a lid body 42 blocking the lower end of the cylindrical body, a liquid absorbing member 6 which sucks the liquid medicine in the container and volatilizes the liquid medicine, and a push-in member 8 which holds the liquid absorbing member and is arranged inside of the cylindrical body, and pushes the lid body and at least partially separates the lid body from the lower end of the cylindrical body. In a state in which the lid body 42 is at least partially separated from the lower end 41a of the cylindrical body 41 by the push-up member 8, a lower end 61a of the liquid absorbing member 6 projects from a lower end 81a of the push-in member 8 pushing the lid body 42 and is brought into contact with the bottom of the container 2.SELECTED DRAWING: Figure 7【課題】薬液を無駄なく揮散させることができる揮散装置を提供する。【解決手段】本発明の揮散装置の一態様は、薬液を収容した容器2と、容器内に位置した下端41aおよび容器の上部に開口した上端41bを有する筒状体41と、筒状体の下端を塞ぐ蓋体42と、容器内の薬液を吸い上げて揮散させる吸液部材6と、吸液部材を保持して筒状体の内部に配置され、蓋体を押して筒状体の下端から少なくとも部分的に分離させる押込み部材8と、を有する。押込み部材8によって蓋体42を筒状体41の下端41aから少なくとも部分的に分離させた状態で、吸液部材6の下端61aが蓋体42を押す押込み部材8の下端81aより突出して容器2の底に接触する。【選択図】図7
