Problem to be solved: to provide an inverted type volatilization apparatus capable of obtaining stable volatilization and diffusion effect without contaminating the surroundings. As a solution means, an overhanging type volatilization apparatus is provided which is fixedly held in the lower container so as to form a wall surface which is connected to the bottom surface and substantially vertical to the bottom surface.周囲を汚すことがなく、安定した揮散および拡散効果が得られる倒立型揮散装置を提供することを課題とする。解決手段として、揮散体を、底面及び該底面と略垂直に連なる壁面を形成するように下容器内に固定保持した倒立型揮散装置を提供する。
