  • METHOD OF MANUFACTURING OPTICAL MEMBER, AND OPTICAL MEMBER
    Publication number: 20220288817
    Abstract: A method of manufacturing an optical member by curing a thermally polymerizable composition by heating includes, in the following order: a first step of filling an inside of a mold with the thermally polymerizable composition in which the mold is configured by disposing a frame-shaped member, with a Young's modulus of 1.0 GPa or more at a polymerization initiation temperature of the thermally polymerizable composition, between two mold members facing each other; and a second step of heating the mold to the polymerization initiation temperature or more.
