    摘要： Provided is a method, including: performing heat treatment, under a state in which a thick core plate glass (2a) having a higher thermal expansion coefficient and a thin surface-layer plate glass (3a) having a lower thermal expansion coefficient are laminated together, so that the laminated portion has a temperature equal to or higher than the lower softening point out of the softening points of the core plate glass (2a) and the surface-layer plate glass (3a), thereby melt-bonding the core plate glass (2a) and the surface-layer plate glass (3a); and then performing cooling so as to attain a temperature less than the lower strain point out of strain points of the core plate glass (2a) and the surface-layer plate glass (3a), to thereby form a compression stress in a surface layer portion (3) corresponding to the surface-layer plate glass (3a) and form a tensile stress in a core portion (2) corresponding to the core plate glass (2a).
