Abstract

A mold set includes: a first mold and a second mold placed so that they sandwich an optical material and face each other; and a first spacer and a second spacer provided between the first and second molds, wherein: the first spacer secures an interval between the first and second molds at a first temperature achieved in a process of pressurizing the optical material; the first spacer shrinks in a mold opening-closing direction more greatly than the second spacer while the first temperature is changing to a second temperature achieved in a process of cooling the optical material; and the second spacer secures the interval between the first and second molds at the second temperature.
