Abstract
A substrate forming mold for forming a substrate by filling a cavity formed between a pair of matching molds 1, 2 with resin, that is, this substrate forming mold has shims 9, 12 disposed at least between a mirror finished surface plate 6 for composing one mold 1 and a stable mold base 8, and in a region inside of a fixed abutting ring 13, depending on fluctuations of plate thickness of formed substrate. As a result, the plate thickness of formed substrate can be adjusted finely, and fluctuations occurring in the radial direction or peripheral direction of the formed substrate can be decreased.
