PURPOSE: To obtain such a material which at one time or gradually discharge products in a desired form by incorporating a fungicide or accelerator for biological growth produced by electric discharge or UV ray into the adsorbent base material.

CONSTITUTION: A fungicide or accelerator for biological growth is incorporated into an adsorbent base material having gas adsorptivity. This fungicide or accelerator for biological growth is such a material that can be adsorbed and maintained on this base material, and is produced by electric discharge and UV-ray (10 - 380nm wavelength) such as ozone-base material, nitrogen oxide, etc. The obtd. adsorbent material containing a fungicide or accelerator for biological growth is used to give the effects of fungicide, oxidization decomposition, or oxygen supply, etc., by discharging the product at one time or gradually in a desired state.
