Abstract
A production process for an optically shaped product, including applying a photosensitive resin composition in a form of a dry film on to a substrate in which a hole opening to a surface thereof is formed so as to cover the hole and performing patterning to form an optically shaped product, wherein the photosensitive resin composition contains a resin comprising a tri- or higher functional epoxy resin and a bifunctional epoxy resin, the bifunctional epoxy resin has a weight-average molecular weight (Mw) of 5,500 to 60,000, the resin has a weight-average molecular weight (Mw) ranging from 4,500 to 11,000, and the mixing ratio by mass between the tri- or higher functional epoxy resin and the bifunctional epoxy resin satisfies (b)/(a)≦1.5, where (a) is the mass of the tri- or higher functional epoxy resin, and (b) is the mass of the bifunctional epoxy resin.
