description PROBLEM TO BE SOLVED: To provide a molding apparatus which improves combination accuracy of molds and improves quality of molded articles by appropriately correcting parallel accuracy of a pair of molds. SOLUTION: The molding apparatus 1 comprises: a pair of top and bottom molds 14 and 24, at least one of which being movably supported by top and bottom press shafts 11 and 21; a lamp unit 40 to heat a glass substrate 30 arranged between the molds 14 and 24 and the molds 14 and 24; a servomotor 45 and a screw jack 46 to mold the glass substrate 30 softened by the above heating under pressure by moving one or both of the pair of molds 14 and 24; and graphite sheets 13 and 23 which prevent heat from the top mold 14 and the bottom mold 24 to the top and bottom press shafts 11 and 21 and is elastically deformable by pressurization.
