PROBLEM TO BE SOLVED: To provide a lens and an assembled lens capable of keeping moldability satisfactorily and preventing the light made incident on an outer peripheral side than an effective diameter from reaching an imaging device and becoming harmful light even when it is an assembled lens positioned by making the lenses directly abut on each other. SOLUTION: The assembled lens 1 is constituted by combining two or more optical lenses 12 and 13. In the assembled lens 1, the optical lens 12 has the effective diameter part, an annular rugged part which is positioned adjacently to the outer periphery of one surface of the effective diameter part and where annular rugged shape is formed, and a plane part positioned on the outside from the annular rugged part on a plane on the annular rugged part side and directly coming into contact with the other lens. Then, a ring-shaped light shielding plate 16 is held between the optical lens 12 and the optical lens 13 directly coming into contact with the plane part of the optical lens 12.
