Disclosed are a compression molding apparatus and a molding die, whereby efficient hot-molding is performed. The compression molding apparatus performs a molding by providing a raw material into the molding die, and applying heat and pressure to the material. The apparatus is provided with: a first molding die, which forms a molding frame that surrounds a region where the raw material is compression-molded; a second molding die, which compresses the raw material provided into the molding frame; and a heat source section, which supports and heats the second molding die. The second molding die has: a first heat pipe, which has one end positioned on the heat source section side, and the other end positioned on the side of a pressing surface that presses the raw material; and a heat insulating layer, which wraps the first heat pipe along the longitudinal direction of the first heat pipe.
