Imaging device

An imaging device, comprising:

• a light source configured to radiate light in at least two different wavelength bands;
• an imaging element configured to acquire signals individually from the light in the at least two different wavelength bands, wherein
• the imaging element includes:
• a first photoelectric conversion unit,
• a second photoelectric conversion unit, and
• a dielectric multilayer film between the first photoelectric conversion unit and the second photoelectric conversion unit, and
• the at least two different wavelength bands include:
• a first wavelength band from 400 nm to 580 nm for use in dermatoglyphic pattern authentication, and
• a second wavelength band of 650 nm or more including near-infrared rays for use in vein authentication;
• a transparent substrate on the imaging element;
• a plurality of image forming lenses between the imaging element and the transparent substrate;
• and
• a light shielding film between a first image forming lens of the plurality of image forming lenses and a second image forming lens of the plurality of image forming lenses.
