Abstract:
According to the present invention, a lens adhesive including a compound represented by General Formula 1 is provided. Pol1-Sp1-L1-Ar-L2-Sp2-Pol2 (General Formula 1) In the formula, Ar is an aromatic ring group represented by General Formula 2-2 and the like. In the formula, Z1 and Z2 each represent a hydrogen atom, a methyl group, and the like; A1 and A2 each represent —S— and the like; X represents C(Rz)2 and the like (where Rz is a substituent, and two Rz's may form a ring); L1 and L2 each represent a single bond, —O—, —OC(═O)—, —OC(═O)O—, —OC(═O)NH—, and the like; Sp1 and Sp2 each represent a single bond or a linking group such as a linear alkylene group; Pol1 and Pol2 each represent a hydrogen atom or a polymerizable group; and a compound represented by General Formula 1 has at least one polymerizable group. Using the lens adhesive, it is possible to provide a cemented lens that is unlikely to deteriorate due to light, and an imaging module having high durability.
