PROBLEM TO BE SOLVED: To provide a volatilization body unit capable of suppressing breakage of a volatilization body when external force acts to a packaging container.SOLUTION: A volatilization body unit (10) comprises: plural volatilization bodies (20) and a packaging container (30) for storing the plural volatilization bodies (20) in a sealed state together, and having flexibility capable of deforming so as to match contours of the plural volatilization bodies (20). A vacuum state is formed in the packaging container (30), and a shape of the packaging container (30) is maintained so as to match the contours of the plural volatilization bodies (20) so as to regulate relative displacement of the plural volatilization bodies (20) to the packaging container (30) by the vacuum state.COPYRIGHT: (C)2016,JPO&INPIT【課題】包装容器に外力が作用したときの揮散体の破損を抑制可能な揮散体ユニットを提供すること。【解決手段】揮散体ユニット(10)であって、複数の揮散体(20)と、複数の揮散体(20)を密封状態でまとめて収容するとともに複数の揮散体(20)の外形に沿うように変形可能な可撓性を有する包装容器(30)と、を備え、前記包装容器(30)の内部に真空状態が形成され、前記包装容器(30)は、前記真空状態の形成により複数の揮散体(20)の当該包装容器(30)に対する相対変位を規制するように複数の揮散体(20)の外形に沿う形状に保持されていること。【選択図】図1
