Abstract: The present invention relates to an evaporation apparatus capable of supplying active ingredients sufficiently and stably. One embodiment of the invention includes a retention vessel keeping a liquid formulation which contains active ingredients, a liquid absorbing mechanism which absorbs the liquid formulation from said retention vessel, an evaporation mechanism which evaporates active ingredients of said liquid formulation absorbed into said liquid absorbing mechanism and adjusting means which adjusts the evaporation of active ingredients.

Abstract: An object of the present invention is to provide a multifunctional gel material including a gel and solid materials, in which the solid materials are moderately dispersed within the gel by adjusting the specific gravities of the gel and the solid materials, or in which the solid materials are always arranged in the same predetermined positions within the gel by dispersing them to the predetermined positions with a positioning means. To achieve this object, the solid materials are dispersed within the gel by using any means. Specifically, the solid materials are dispersed within the gel by adjusting the specific gravity of the solid materials with the specific gravity of the gel. Furthermore, the solid materials are moderately dispersed within the gel by being appropriately arranged by a positioning means.
