PROBLEM TO BE SOLVED: To prevent the problems that unevenness in the physical properties of a molded article or a defective molding from occurring by preventing raw materials for which a plurality of kinds of raw materials are mixed from being separated prior to molding. SOLUTION: For the mixed raw material G, a plurality of kinds of granular raw materials having different specific gravities or shapes are mixed by an stirring device 30 by a specified ratio. This feeding device 1 for the mixed raw material throws in the mixed raw material G into a hopper 11 of a molding device by dropping it. A guide pipe 5 is attached to the feeding port 6 at the lower part of a tank part 4 for storing the raw material for one time on the top of the hopper 11. At the same time, the distal end of the guide pipe 5 reaches the inside of the hopper 11. COPYRIGHT: (C)2004,JPO
