PROBLEM TO BE SOLVED: To provide a method for producing a laminated glass which is lightweight and has high strength, and can form a functional layer on a surface thereof.SOLUTION: A method for producing a laminated glass formed by laminating first and second glass substrates includes the steps of: preparing a first glass substrate having a first surface and a second surface, having a thickness of 1.5 mm or less, and containing an alkali metal oxide, and performing chemical strengthening treatment of at least the first surface of the first glass substrate; preparing a second glass substrate having a third surface and a fourth surface and having a thickness of 1.5 mm or less, and forming a functional part on the third surface and/or the fourth surface of the second glass substrate through a heat treatment step, wherein a region of the second glass substrate not formed with the functional part is chemically strengthened; and bonding the first and second glass substrates through an adhesive layer so that the second surface and the third surface are located inside.SELECTED DRAWING: Figure 1

    【課題】軽量高強度で、表面に機能層を形成することが可能な積層ガラスの製造方法。【解決手段】第1および第2のガラス基板が積層されてなる積層ガラスの製造方法は、第1の表面および第2の表面を有し厚さが1.5mm以下でありアルカリ金属酸化物を含有する第1のガラス基板を準備し、該第1のガラス基板の少なくとも第1の表面を、化学強化処理するステップと、第3の表面および第4の表面を有し、厚さが1.5mm以下の第2のガラス基板を準備し、該第2のガラス基板の第3の表面および/または第4の表面に、熱処理工程を経て、機能部を形成するステップであって、第2のガラス基板の前記機能部が形成されていない領域は、化学強化処理されている、ステップと、接着層を介して、第1および第2のガラス基板を、第2の表面および第3の表面が内側となるようにして接合するステップと、を有する。【選択図】図1
