Abstract:
An image pickup lens LN includes four blocks of lens blocks Ci (i=0 to 4). Lens substrate Li2 is different in material from lens portions Li1 and Li3. First lens block C1 has positive power, second lens block C2 has negative power, and fourth lens block C4 has a concave shape facing an image side in a paraxial region. At least one of lens portions with a concave shape in the paraxial region satisfies the conditional expression νn
