Partial and even to reduce the structure overall size containing a volatile drug to suppress the volatilization amount reduction of volatile agents by securing surface area, and which may contact the inner wall of the container of the surface area of the entire structure to minimize, to prevent contamination of the container as well as avoid the volatilization of the volatile agent is prevented. Is a corrugated body by forming a rod in a wave shape, a wavy body of a plurality of, a three-dimensional structure is constituted by joining by crossed at its top portion to each other, the three-dimensional structure, volatility with volatile It is formed with a resin composition containing a drug, prepared by incorporating a volatile drug, a volatile drug-containing structure which can be stripped from the surface by bleeding on the surface of the three-dimensional structure used.揮散性薬剤を含有する構造体全体の大きさを小さくしても、表面積を確保して揮散性薬剤の揮散量低下を抑え、かつ、構造体全体の表面積のうち容器の内壁に接触しうる部分をできるだけ少なくし、揮散性薬剤の揮散が妨げられるのを避けるとともに容器の汚染を防止する。棒状体を波状に形成して波状体とし、複数本の波状体を、その頂部同士で交差させて接合させることにより構成した立体構造体であって、立体構造体は、揮散性を有する揮散性薬剤を含有させた樹脂組成物を用いて形成されており、練り込まれた揮散性薬剤は、立体構造体の表面にブリードしてその表面から揮散することが可能な揮散性薬剤含有構造体を用いる。
