(General Formula 1)
In the formula, Ar is an aromatic ring group represented by General Formula 2-2 and the like.
In the formula, Z
1
and Z
2
each represent a hydrogen atom, a methyl group, and the like; A
1
and A
2
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); L
1
and L
2
each represent a single bond, —O—, —OC(═O)—, —OC(═O)O—, —OC(═O)NH—, and the like; Sp
1
and Sp
2
each represent a single bond or a linking group such as a linear alkylene group; Pol
1
and Pol
2
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.
