In order to provide an enamel frit composition for a low-expansion crystallized glass, capable of producing an enamel coating excellent in abrasion resistance and acid resistance without occurrence of cracks by using glass powder which does not contain any harmful component such as PbO, and to provide an enamelcoated low-expansion crystallized glass plate using the enamel frit composition, the enamel frit composition for a low-expansion crystallized glass essentially consists 40-98 wt% glass powder, 1-55 wt% coloring pigment, and 054 wt% filler. The glass powder consists, by weight, of 55-72% SiO2, 4-8% Al2O3, 14-22% B2O3, 2-4% BaO, 5.1-15% Na2O, 0-2% Li2O, 0-2.8% K2O, and 0-2% F2.
