Abstract
According to the present invention, a lens adhesive including a compound represented by General Formula 1 is provided.Pol-Sp-L-Ar-L-Sp-Pol  (General Formula 1) In the formula, Ar is an aromatic ring group represented by General Formula 2-2 and the like. In the formula, Zand Zeach represent a hydrogen atom, a methyl group, and the like; Aand Aeach represent —S— and the like; X represents C(Rz)and the like (where Rz is a substituent, and two Rz's may form a ring); Land Leach represent a single bond, —O—, —OC(═O)—, —OC(═O)O—, —OC(═O)NH—, and the like; Spand Speach represent a single bond or a linking group such as a linear alkylene group; Poland Poleach 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.
