(57) [Abstract] [Purpose] If you want to volatilize and use fragrances for a long period of time, if it is in a liquid state, store it in a sealed container as it is and open a part of the container. Means such as adsorbing to the fine particles and fixing them to a certain shape with a binder or the like as required are adopted. However, with such conventional means, generally, a large amount of fragrance is volatilized in the beginning, and the volatilized amount tends to decrease rapidly with the passage of time. Moreover, it is difficult to keep volatilization for a long time. An object of the present invention is to solve the above-mentioned drawbacks and to provide a sustained-release volatilizer which can maintain the volatilization amount (sustained-release amount) for a long period of time evenly. The sustained-release volatilizer of the present invention is characterized in that one or more terpenoids are adsorbed on an oil-absorbing reticulated polymer material together with an antioxidant or further together with a non-combustible organic compound.
