<P>PROBLEM TO BE SOLVED: To suppress stress concentration arising in a mold for forming which penetrates a positioning component, in a mold set for forming an optical element. <P>SOLUTION: The mold set for forming an optical element 10 includes the first mold (upper mold 11) and the second mold (lower mold 12) which are arranged oppositely in putting a molding raw material 100 between them, and a positioning component 13 which is arranged between the first mold (11) and the second mold (12) and positions the molding raw material 100, where the first mold (11) penetrates the positioning component 13 and presses the molding raw material 100 at the molding surface 11a at the tip, and the diameter of partial 11e intercalated into the positioning component 13 of the first mold 11 becomes so large that it goes to the root side (diameter D2) from the molding surface 11a (diameter D1). <P>COPYRIGHT: (C)2012,JPO&INPIT |
