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.
