PROBLEM TO BE SOLVED: To provide a compression molding apparatus and compression molding method, capable of readily manufacturing in a short time a molded body with high quality and high dimensional accuracy. SOLUTION: A compression molding apparatus 1 is a compression molding apparatus for compressing and molding a bonded magnet, and comprises an outer die 2 for compression and molding, and an upper punch 7 and a lower punch 8 for compressing a molding material 15 filled in the outer die 2. The outer die 2 is constituted along the axial direction by a heat part 3 for heating the molding material 15, a cooling part 5 for cooling the molding material 15, and a heat insulating part 4 positioned therebetween. The upper punch 7 and lower punch 8 can axially move within a molding space 21 relative to the outer die 2, respectively. A gap part 73 is formed in an outer periphery of a part, excluding the vicinity of a pressing face 71 of the upper punch 7, and a gap part 83 is formed in an outer periphery of a part, excluding the vicinity of a pressing face 81 for the lower punch 8. These gap parts 73, 83 exhibit heat insulating effects.
