a functional filler consisting of 60 wt % of a porous material having pores and 40 wt % of a silicone fluid, wherein the pores of the porous material are filled with the silicone fluid; ceramic powder; and a pigment, wherein the silane compound is methyltrimethoxysilane, wherein the inorganic binder is silica sol consisting of 30 wt % of silicon dioxide having a diameter of 0.2 to 1.0 μm and 70 wt % of water, wherein the porous material is fumed silica, wherein the silicone fluid is methylphenyl silicone fluid, wherein the ceramic power is consisted of quartz, monzonite, strontium, and vanadium, wherein, with respect to 100 parts by weight of the inorganic binding agent, the nonstick ceramic coating composite consists of 7 parts by weight of the functional filler, 15 parts by weight of the ceramic powder, and 5 parts by weight of the pigment. ### Claim 2 A nonstick ceramic coating composite for a heating kitchen utensil consisting of: an inorganic binding agent consisting of 40 wt % of a silane compound and 60 wt % of an inorganic binder; a functional filler consisting of 40 wt % of a porous material having pores and 60 wt % of a silicone fluid, wherein the pores of the porous material are filled with the silicone fluid; ceramic powder; and a pigment, wherein the silane compound is ethyltrimethoxysilane, wherein the inorganic binder is consisted of 30 wt % of silica sol and 30 wt % of alumina sol, the silica sol consisting of 30 wt % of silicon dioxide having a diameter of 0.2 to 1.0 μm and 70 wt % of water and the alumina sol consisting of 20 wt % of aluminum oxide having a diameter of 0.2 to 1.0 μm and 80 wt % of water, wherein the porous material is fumed silica, wherein the silicone fluid is methylphenyl silicone fluid, wherein the ceramic power is consisted of quartz, monzonite, strontium, and vanadium, wherein, with respect to 100 parts by weight of the inorganic binding agent, the nonstick ceramic coating composite consists of 12 parts by weight of the functional filler, 20 parts by weight of the ceramic powder, and 10 parts by weight of the pigment.
