PROBLEM TO BE SOLVED: To obtain a chemical impregnation body with a large chemical transpiration rate per unit time without growing in size.SOLUTION: The chemical impregnation body 1 is obtained by impregnating the volatile chemical into a substrate with communication pores. The chemical impregnation body 1 is stored in a chemical cartridge 2 of a fan type chemical diffusion apparatus 10. The air is struck to the chemical impregnation body 1 by a blower 12 of the fan type chemical diffusion apparatus 10 to diffuse the chemical.COPYRIGHT: (C)2012,JPO&INPIT【課題】単位時間当たりの薬剤蒸散量の多い薬剤含浸体を大型化せずに得る。【解決手段】連通気孔を有する基材に揮発性の薬剤を含浸させて薬剤含浸体1を得る。薬剤含浸体1は、ファン式薬剤拡散装置10の薬剤カートリッジ2に収容する。ファン式薬剤拡散装置10の送風機12により空気を薬剤含浸体1に当て、薬剤を拡散させる。【選択図】図1
