PROBLEM TO BE SOLVED: To provide a volatilization device capable of efficiently volatilizing a volatilizing agent.SOLUTION: An operating lever 5 rotates about a rotary shaft R between a standby position where, before the other end side portion presses a container body 3, a discharge valve 51 closes a discharge hole 36A and an exhaust valve 52 blocks communication between a head space and the outside through an exhaust hole 35A and a discharge position where the other end side portion presses the container body 3, the discharge valve 51 opens the discharge hole 36A and the exhaust valve 52 blocks communication between the head space and the outside through the exhaust hole 35A. When the operating lever 5 is located between the standby position and the discharge position, the exhaust valve 52 communicates the head space with the outside through the exhaust hole 35A.SELECTED DRAWING: Figure 1
