PURPOSE: To achieve higher fragrance effect by a method wherein a proper number of air tiny holes are cut at the upper part of a surrounding wall of a container sealing an aroma agent on the bottom thereof while a part for inserting an artificial flower is arranged at the center or the like of the container to obtain such a synergistic action of vision and olfaction as if emanating fragrance from the artificial flower.

CONSTITUTION: A proper number of air tiny holes 3 are cut at the upper part of a surrounding wall of an external shell 1 for a hemispherical hollow container. A disc-shaped bottom plate 2 is mounted on the bottom of the external shell 1 while a particulate aroma agent 5 is placed on the top surface of the bottom plate 2. Moreover, a cylinder body 4 is erected at the center of the external shell 1 while a hood body 6 having a through hole at the center of a small body cut thereinto is fitted at the upper end part of the cylinder body 4. Then, an artificial flower 7 is fitted into the hood body 6 and the cylinder body 4. As a result, an aroma device emanates fragrance while the artificial flower 7 or the like is inserted to decorate a room.
