The purpose of the present invention is to secure the surface area of a structure containing a volatile medicinal agent to thereby prevent the reduction in the volatilization volume of the volatile medicinal agent even when the whole size of the structure is reduced, and to reduce the surface area of a portion of the whole surface of the structure which can contact with the inner wall of a container as possible to thereby avoid the prevention of the volatilization of the volatile medicinal agent and prevent the contamination of the container. A structure containing a volatile medicinal agent is used, which is a three-dimensional structure produced by shaping each of rod-like bodies into a wavy form to produce multiple wavy bodes and then joining the multiple wavy bodies to each other with the multiple wavy bodies being crossed each other at top parts thereof, wherein the three-dimensional structure is formed using a resin composition containing a volatile medicinal agent having a volatile property so that the volatile medicinal agent kneaded into the three-dimensional structure can bleed out on the surface of the three-dimensional structure and can be volatilized from the surface.本發明之目的在於即便縮小含有揮發性藥劑之結構體整體之大小,亦確保表面積而抑制揮發性藥劑之揮發量降低,並且,儘量減少結構體整體之表面積中會與容器之內壁接觸之部分,避免阻礙揮發性藥劑之揮發,並且防止容器之污染。本發明係使用一種含有揮發性藥劑之結構體,其係將棒狀體形成為波狀而製成波狀體,藉由使複數根波狀體於其頂部彼此交叉並接合而構成之立體結構體,立體結構體使用含有具有揮發性之揮發性藥劑之樹脂組合物而形成,所捏合之揮發性藥劑可滲出至立體結構體之表面並自該表面揮發。11、12‧‧‧波狀體12a‧‧‧第1頂部12b‧‧‧第2頂部
