| Summary: | The present invention relates to a method of producing a molded article. More specifically, it relates to a method of producing a highly accurate molded article such as an optical fiber fixing member, a waveguide, a lens, a microlens array, a prism or a disk substrate from a preform by a molding method.
A molded article having a highly accurate outer form accuracy, including various optical products, is produced from a preform having a simple form by a press-molding, in which a fine pattern can be highly accurately transferred and no burr is formed. A first mold member having a concave portion with an inner surface made of a molding surface and a second mold member which is to be opposed to the first mold member and has a molding surface are used to press-mold the preform. The preform is shaped in a polyhedral form to permit fitting of the preform in the concave portion of the first mold member. |
