PROBLEM TO BE SOLVED: To provide an active energy ray-curing type composition which is used for optical members, and gives cured products having excellent mold release properties from molds, excellent adhesiveness to transparent substrates, compatible with a high refractive index. SOLUTION: This active energy ray-curing type composition for optical members contains the following components (A) to (E): (A): a di(meth)acrylate represented by formula (1), wherein X is -C(CH<SB>3</SB>)<SB>3</SB>- or S; R<SB>1</SB>and R<SB>3</SB>are each independently H or methyl; R<SB>2</SB>and R<SB>4</SB>are each independently H, methyl or ethyl; (l) and (m) are each independently an integer of 0 to 4, (B): a compound having two aromatic rings and one (meth)acryloyl group, (C): a compound having one aromatic ring and one (meth)acryloyl group, (D): a compound having three or more (meth)acryloyl groups, and (E): if necessary, an ethylenic unsaturated group-containing compound except the components (A) to (D).
