Abstract:
Provided is an imaging lens unit which blocks or reduces infrared light over a wide region at a wavelength of 650-1100 nm and suppresses deposition and bleed-out of an infrared light absorbent. In a wafer lens laminated body (1), i.e., one example of the imaging lens units of this invention, wafer lenses (10, 30) wherein resin sections (14, 16, 34, 36) composed of a photo-curable resin are formed on glass substrates (12, 32) are laminated in two or more layers, one or two types of infrared light absorbents are added to the resin sections (14, 16, 34, 36), and the absorbing regions of the respective infrared light absorbents are different from each other.
