摘要:
Disclosed is a mold used as a bottom mold for manufacturing glass molded bodies by accepting molten glass droplets that are dripped in and by compression molding of the molten glass droplets in conjunction with a top mold. The mold is provided with a base material that has a mold surface for compression molding of molten glass drops, and a coating layer formed on the mold surface. The surface of the coating layer formed on the mold surface has a rough surface region that comprises the center of the mold surface, and a mirror finished region that surrounds the outside of the rough surface region and has a lower arithmetic mean roughness Ra than the rough surface region.
