Summary:PURPOSE:To restrain defects in curvature, cracks or wrinkles of a glass product by improving a temperature difference in the whole metal mold. CONSTITUTION:Copper is used as a heat conductive layer 119, and an air insulating layer is used as a heat insulating layer 120. Inside a side periphery molding surface 111, the heat conductive layer 119 and the heat insulating layer 120 further on the inside in the thickness direction are arranged over the side periphery molding surface 111 from the vicinity of a corner molding surface 110.
