PROBLEM TO BE SOLVED: To fill a filler by dispersing the filler uniformly in a molded body, or by filling the filler in a higher density comparing with conventional method, or allowing a plurality of fillers to have a specific filled density distribution tendency in the molded body. SOLUTION: A reactive stock solution is reacted to be polymerized in a state wherein a centrifugal force is added to a filler 7 and a reactive stock solution which exist in a mold. Therefore, even if the filler 7 is unevenly distributed peripherally in the mold, the filler 7 is dispersed uniformly peripherally in the mold by the centrifugal force. Further the reactive stock solution is also stuck to an inner peripheral surface of the mold by the centrifugal force to start a polymeric reaction. Consequently, in the obtained molded body, that in which the filler 7 is dispersed at least uniformly peripherally in the mold body is obtained. As the filler, two or more kinds of fillers of different specific gravities 7a, 7b can be also filled in the molded body. In that case, the filler of a larger specific gravity 7a becomes rich to an outer peripheral side of the molded body, and the filler of a smaller specific gravity 7b becomes rich to an inner peripheral side of the molded body. |
