  • Publication number: 20130118685
    Abstract: A wafer lens member producing method includes post-curing lens portions made of a light-curing resin formed on at least one face of a substrate so as to promote curing of the light-curing resin. The post-curing includes first post-curing and second post-curing. The first post-curing performs heating at a first post-curing temperature, which is a glass transition temperature of the light-curing resin to the glass transition temperature+100° C., for 30 minutes to two hours. The second post-curing performs heating at a second post-curing temperature, which is lower than the glass transition temperature, and lower than the first post-curing temperature by 25° C. or more, for three hours to six hours.
