PROBLEM TO BE SOLVED: To provide a volatilization body and a volatilization device which can adjust a volatilization amount, and do not require assembling work.SOLUTION: A main body 42 of a volatilization body is formed in a self-standing shape by forming a sheet body 43 in a cylindrical shape. In a lengthwise direction of the main body 42 of the volatilization body, first to seventh telescopic members 51-57 are set, and an extended state 41 or a folded state 58, in which each of the telescopic members 51-57 is either extended or contracted in the lengthwise direction of the main body 42 of the volatilization body, can be formed selectively. The vertically adjacent telescopic members 51-57 are provided consecutively. While each of the telescopic members 51-57 is in the folded state 58, the telescopic members 51-57 in the folded state 58 are laminated. The main body 42 of the volatilization body is configured so as to be a tapered shape toward the upper part while each of the telescopic members 51-57 is in a self-standing state.COPYRIGHT: (C)2015,JPO&INPIT【課題】揮散量の調整を可能としつつ、組み付け作業を要しない揮散体及び揮散装置を提供する。【解決手段】シート体４３を筒状に形成して揮散体本体４２を自立可能な形状に形成する。揮散体本体４２の長さ方向に第一～第七伸縮部５１～５７を設定し、各伸縮部５１～５７を揮散体本体４２の長さ方向に伸張した伸張状態４１又は縮小した折畳状態５８を選択的に形成可能とする。上下に隣接する伸縮部５１～５７を連続的に設け、各伸縮部５１～５７を折畳状態５８にした状態で折畳状態５８の伸縮部５１～５７が積層されるように構成する。揮散体本体４２は、各伸縮部５１～５７を伸張状態４１にして自立させた状態で、上方へ向かうに従って先細り形状となるように構成する。【選択図】図２
