PROBLEM TO BE SOLVED: To provide a molten resin lump supply device capable of certainly dropping a molten resin lump in the cavity of a female mold for compression molding without delaying timing from a cylindrical transfer guide for feeding the molten resin lump to the cavity of the female mold for compression molding. SOLUTION: In the molten resin lump supply device provided with a vibration producing means 16 for applying vibration to the cylindrical transfer guide 9 above the female mold for compression molding, the molten resin lump 13 is smoothly dropped in the cavity of the female mold for compression molding in a short time without being bonded to the inner peripheral surface of the housing chamber of the transfer guide and the timing irregularity of a falling time is eliminated to facilitate predetermined control.
