PROBLEM TO BE SOLVED: To heat emphatically a surface layer part of glass facing to a molding surface provided on a molding tool, while maintaining the molding tool at a low temperature.SOLUTION: In a processing method of a glass sheet for molding the glass sheet G1 into a shape obtained by copying a molding surface 1a provided on a molding tool 1 by heating the glass sheet G1 arranged on the molding tool 1, a laser beam LB transmitted by the molding tool 1 and absorbed by the glass sheet G1 is applied to the glass sheet G1 through the molding tool 1, to thereby heat the glass sheet G1.SELECTED DRAWING: Figure 1 【課題】成形型を低温に維持しつつ、成形型に設けられた成形面に面するガラスの表層部を重点的に加熱する。【解決手段】成形型１に配置したガラス板Ｇ１を加熱して、ガラス板Ｇ１を成形型１に設けた成形面１ａに倣った形状に成形するガラス板の加工方法であって、成形型１を透過し且つガラス板Ｇ１で吸収されるレーザＬＢを、成形型１を通してガラス板Ｇ１に照射することで、ガラス板Ｇ１を加熱する。【選択図】図１
