There are provided a near-infrared cut filter that effectively uses near-infrared absorbing glass and a near-infrared absorbing dye and is excellent in a near-infrared shielding property, and a high-sensitivity solid-state imaging device including the same. A near-infrared cut filter includes: a near-infrared absorbing glass substrate made of CuO-containing fluorophosphate glass or CuO-containing phosphate glass; and a near-infrared absorbing layer containing a near-infrared absorbing dye (A) and a transparent resin (B), on at least one principal surface of the near-infrared absorbing glass substrate, wherein an average value of a transmittance in a 400 nm to 550 nm wavelength range is 80% or more, and an average value of a transmittance in a 650 nm to 720 nm wavelength range is 15% or less.
