To convey a glass plate having a longitudinal posture and accompanying a direction change with a high speed.SOLUTION: A method for manufacturing a glass plate includes a conveyance step of supporting and conveying an upper end portion of a glass plate G3 having a longitudinal posture. The conveyance step comprises: the first conveyance step of conveying the glass plate G3 in a first direction along a direction perpendicular to a main surface; and the second conveyance step of conveying the glass plate G3 in a second direction along a direction parallel to the main surface. When the conveying direction of the glass plate is changed to the second direction from the first direction, a lower end portion of the main surface G3y is supported by the roller 41 of a support part 4 from the front side in the conveying direction of the glass plate G3 conveyed in the first direction.SELECTED DRAWING: Figure 1 【課題】方向変更を伴う縦姿勢のガラス板の搬送を高速化する。【解決手段】縦姿勢のガラス板Ｇ３の上端部を支持して搬送する搬送工程を備えるガラス板の製造方法である。搬送工程は、ガラス板Ｇ３を主表面に垂直な方向に沿う第一方向に搬送する第一搬送工程と、第一搬送工程の後に、ガラス板Ｇ３を主表面に平行な方向に沿う第二方向に搬送する第二搬送工程とを備える。ガラス板の搬送方向を第一方向から第二方向に変更する際に、第一方向に搬送されるガラス板Ｇ３の搬送方向の前方側から主表面Ｇ３ｙの下端部を支持部４のローラ４１で支持する。【選択図】図１
