PURPOSE: A charcoal container is provided to prevent reduction of the natural characteristics of charcoal such as deodorization, adsorption, and far-infrared ray emission while preventing the sticking of the charcoal powder by adding reinforcing resin to fine coal power of black oaks, thereby maintaining plants or food fresh for a long time and promoting the growing of plants. CONSTITUTION: A charcoal container is manufacturing by adding 20-50wt% of unsaturated polyester resin to 100wt% of fine charcoal, mixing the unsaturated polyester resin with the fine charcoal, and casting the mixture to mold as a desired shape, wherein an inorganic filler is added by less than 15wt% with respect to 100wt% of the fine charcoal powder of black oaks.
