摘要： A manufacturing method for a laminated glass in which a plurality of glass plates are laminated, includes a first main forming step of heating a first glass plate to a first softening point or higher to perform a main forming; a second main forming step of heating a second glass plate to a second softening point or higher to perform the main forming; a first finish forming step of bending and forming the first glass plate into a desired shape; and a second finish forming step of bending and forming the second glass plate into a desired shape. The first and second main forming steps are performed by using a same forming die. A first condition for lowering a temperature of the first glass plate to below the first softening point and a second condition for the second glass plate are different from each other.
