PROBLEM TO BE SOLVED: To manufacture a crystallized glass substrate which has an antidazzle characteristic capable of properly scattering light generated from lighting and the like, and at the same time has a proper glossy feeling. SOLUTION: In a manufacturing method of a crystallized glass substrate by passing molten glass between a pair of molding rolls, roll-molding it and then firing it, the method is characterized in that the surface of at least one roll of the pair of molding rolls is roughened by a sandblast method, and then polished so that the average surface roughness (Ra) of the surface of the roughened roll becomes small.
