The present invention relates to a mold for producing glass articles comprising a glass-made mold base, an intermediate layer formed by a silicon carbide and/or silicon nitride film, and an uppermost layer formed by a carbon film. Since the mold for producing glass articles exhibits an excellent bonding between the glass-made mold base and the uppermost layer formed by the carbon film, peeling of the uppermost layer can be prevented. Therefore, the function of the uppermost layer as an adhesion-prevention layer against the glass to be molded can be exhibited for a long time, causing an economic advantage since the life of the mold can be lengthened. In addition, since the maximum surface roughness of the working surface of the mold can be reduced and the surface shape accuracy can be maintained, a molded glass article exhibits excellent surface accuracy without optical defects.
