Abstract

PURPOSE: To obtain a reflecting mirror of a large diameter with good accuracy at a low cost by interposing the fluid liquid of the specific mirror surface forming agent between a reflecting mirror rough base material having been roughened nearly to predetermined curvature and surface accuracy and a molding mold, and allowing the same to harden.
CONSTITUTION: A reflecting mirror rought base material 3 is made nearly to predetermined curvature and surface accuracy with metals, glass or the like. Next, a molding mold 1 having been finished with good accuracy is lowered into the rough base material 3 having been put therein with a liquid-form mirror surface forming agent 2 (photosetting resin, thermosetting resin or thermoplastic resin in a fluid state), by aligning their central axes, and is then opposed thereto by leaving a suitable distance (to be determined depending upon the accuracy of the rough base material 3), thence it is allowed to solidify by polymerization or set by cooling (in the case of thermoplastic polymer). In order to allow the mirror surface forming agent 2 to part easily from the mold 1 and base material 3, a material having poor adhesiveness to the molding mold 1 and has good adhesiveness to the base material 3 is selected for the forming agent 2, whereby the occurrence of unevenness on the mirror surface by the use of release agent is obviated. Afther the setting, the mirror surface base body 2 is taken out and a reflecting material is attached on the reflecting surface, whereby the reflecting mirror is made.
