PROBLEM TO BE SOLVED: To prevent a chemical from leaking due to being sealed when not in use, to release the seal by a simple operation at the time of use, and to measure the amount of the chemical evaporated when attached to a heating type chemical evaporation device. Provide a drug storage container that is easy to control. SOLUTION: This is a drug storage container made of a heat-resistant member applied to a drug evaporation device provided with a heating mechanism, and a container body 20 having a concave storage portion 11 for storing the drug and a first engaging portion 23. It has a gas barrier inner lid 22 that covers and seals the storage portion, a second engaging portion 29 that engages with the first engaging portion, and a ventilation hole 15, and engages with the container body so as to cover the inner lid. It has an outer lid 24 to be combined and an opening member 26 for opening the inner lid, and when the container body and the outer lid are engaged with each other, or when the drug storage container is attached to the drug evaporator, the inner lid 24 is provided. The lid is torn by the opening member and the storage portion is opened.
