PROBLEM TO BE SOLVED: To provide a method capable of producing a glass plate having a bent part, in which flatness and smoothness of a planar part are high.SOLUTION: A glass flat plate 20 is heated by radiation in the state where a first part 21 of the glass flat plate 20 is held by first and second heat insulation materials 31, 32. Thereafter, second parts 22a, 22b of the glass flat plate 20 which are not held by the first and second heat insulation materials 31, 32 are bent. |
