Zusammenfassung: | According to the method for manufacturing the glass plate, the glass plate comprises a first main surface and a second main surface opposite to the first main surface, and the first main surface and the second main surface comprise curved surfaces. The method for manufacturing the glass plate comprises the following steps: arranging the glass plate in a manner that the first main surface of the glass plate is opposite to a lower mold containing a curved surface, arranging a pressing part in a manner that the pressing part is opposite to the second main surface of the glass plate supported by the lower mold, and heating the glass plate. And a pressing part which can be lifted and lowered, is provided only on a part of the second main surface and on the peripheral edge of the second main surface, presses the second main surface by the weight of the pressing part, and is in a state in which only a part of the second main surface and the peripheral edge are pressed during the heating.
