Image pickup lens, image pickup apparatus, mobile terminal, and manufacturing method of image pickup lens

摘要

An image pickup lens includes a first lens block with a positive refractive power, a second lens block with a negative refractive power, and an aperture stop. The first lens block includes a first lens substrate, and lens portions 1a and 1b arranged on the first lens substrate. The lens portions 1a and 1b are different from the first lens substrate in at least one of a refractive index and an Abbe number. The second lens block includes a second lens substrate, and lens portions 2a and 2b arranged on the second lens substrate. The lens portions 2a and 2b are different from the second lens substrate in at least one of a refractive index and an Abbe number. The image pickup lens satisfies predetermined conditions relating to a refractive index of the lens portion 2b, and composite thicknesses of the first lens block and the second lens block.
