摘要 |
<p>A cylindrical base material having an outer and inner at least two layer structure is produced by using a cylindrical molded body made of a low-refractive-index material as a mold, and forming at least one layer made of a layer-forming material having a relatively high refractive index in the inner surface of the cylindrical molded body by the rotational molding, wherein the centrifugal force during the rotational molding is changed. <IMAGE></p> |
