摘要：
A desired temperature distribution is efficiently formed on a glass sheet by a simple structure without lowering heat efficiency within a furnace. A heating furnace conveys a bending mold of a glass sheet and a radiation-heating device is provided in the heating furnace. A first group of a plurality of heating elements are fixed on an inner wall surface of the heating furnace. A second group of a plurality of heating elements are disposed separably from an inner wall surface of the heating furnace.
