PROBLEM TO BE SOLVED: To provide a patterned crystallized glass article having sufficient strength and no pinhole defect in an end face thereof. SOLUTION: The patterned crystallized glass article includes a crystallized glass layer A formed by fusion-bonding a plurality of crystalline glass small bodies to each other and crystallizing these, and a crystallized glass layer B fusion-bonded to at least a part of an end face of the crystallized glass layer A and formed by crystallizing a crystalline glass plate B up to the central part, wherein the crystallized glass layer A includes at least one kind of crystal selected fromβ-wollastonite and diopside as a main crystal, and the crystallized glass layer B includes at least one kind of crystal selected fromβ-wollastonite and diopside as a main crystal and has a thickness of≤6 mm.
