Abstract
A resin composition includes a urethane (meth)acrylate (A), a monofunctional (meth)acrylate (B) having an alicyclic skeleton represented by any of Formulae (1) to (3), and a polymer (C) of a monofunctional (meth)acrylate monomer (c1) having an alicyclic skeleton represented by any of Formulae (1) to (3). A content of the polymer (C) is 15 parts by mass or less with respect to 100 parts by mass of the resin composition.
