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.
