Abstract
There are provided an infrared transmission filter, which is inexpensive, is capable of being sufficiently made lighter and thinner, has no incident angle dependency, and is excellent in permselectivity for infrared light, and an imaging device, which employs such an infrared transmission filter. An infrared transmission filterincludes an infrared transmission base materialselectively transmitting light in an infrared wavelength range; and a short wavelength side infrared absorbing filmformed on one side of the infrared transmission base materialand containing a near-infrared absorbent having an optical absorption edge on a short wavelength side of a transmission wavelength band of the infrared transmission base material. An imaging device includes the infrared transmission filter
