1. A photocurable resin composition comprising the following ingredients (A), (B), (C) and (D):
(A) a linear chain epoxy resin represented by the following general formula (1):wherein m indicates an integer of from 2 to 10, and R1 and R2 each represent a hydrogen atom or a fluorine atom;
(B) an alicyclic epoxy resin having at least two epoxy groups in one molecule thereof; (C) a phosphorus fluoride-based photopolymerization initiator; and (D) an oxetane compound having at least one oxetanyl group in one molecule thereof, wherein a content of ingredient (A) is within a range of from 10 to 75% by weight of all the resin ingredients in the composition, a content of ingredient (B) is within a range of from 25 to 75% by weight of all the resin ingredients in the composition, a content of ingredient (C) is within a range of from 0.01 to 7 parts by weight of all the resin ingredients in the composition, and a content of ingredient (D) is within a range of from 3 to 30% of all the resin ingredients.
