Abstract:
There are provided a near-infrared cut filter having a sufficient near-infrared blocking property and being capable of reducing or preventing, in a solid-state imaging device using the near-infrared cut filter, occurrence of a phenomenon that an object which did not exist on the original subject appears in a taken image, and also a highly sensitive solid-state imaging device having the near-infrared cut filter. A near-infrared cut filter includes a stack having a near-infrared absorbing glass substrate and a near-infrared absorbing layer containing a near-infrared absorbing dye and a transparent resin on at least one main surface of the near-infrared absorbing glass substrate, and a dielectric multilayer film formed on at least one main surface of the stack, wherein maximum transmittance at an incident angle of 31 to 60 degrees with respect to light with a wavelength of from 775 to 900 nm is 50% or less.
