PROBLEM TO BE SOLVED: To provide a ceramic color composition by which a ceramic color layer containing no lead and having excellent oxidation resistance can be obtained. SOLUTION: The ceramic color composition essentially consists of, by mass, 40 to 90% lead-free glass powder, 1 to 60% heat resisting pigment powder and a 0 to 59% refractory filler. The lead-free glass powder consists essentially of, by mass based on the following components, 1 to 50% SiO2 , 1 to 30% B2 O3 , 1 to 25% Bi2 O3 , 1 to 20% Al2 O3 , 1 to 20% TiO2 +ZrO2 , 0.3 to 20% Li2 O+Na2 O+ K2 O, 0.1 to 10% P2 O5 +V2 O5 +SnO2 , 0 to 10% ZnO, 0 to 10% Fe2 O3 +CuO, 0 to 10% CeO2 , 0 to 10% La2 O3 and 0 to 5% F.
