A cemented lens comprises first, second and third optical elements respectively formed by different solid materials, the third and first optical elements being cemented to each other, and the first and the second optical elements being cemented to each other, wherein both an incident surface and an exit surface of the first and second optical elements are refracting surfaces, and the following conditional expressions are satisfied: |.DELTA..theta.gF1|>0.0272 |.DELTA..theta.gF2|>0.0272 .DELTA..theta.gF1.times..DELTA..theta.gF2<0 .phi.1.times..phi.<0 where .DELTA..theta.gF1 and .DELTA..theta.gF2 are respectively anomalous dispersion characteristics of the materials for the first and the second optical elements with respect to a g line and an F line, and .phi.1 and .phi.2 are respectively refracting powers of the first and second optical elements when both the incident surface and the exit surface of the first and the second optical element are surfaces in contact with air.
