Ir cut filter

An IR cut filter to block infrared light, the IR cut filter comprising:

• an infrared light absorber configured to absorb the infrared light;
• and
• an infrared light reflector configured to reflect the infrared light,
• wherein the infrared light absorber has a light transmission property of 50% transmittance with respect to a wavelength in a wavelength band of 620 nm to 670 nm,
• wherein the infrared light reflector has a light transmission property of 50% transmittance with respect to a wavelength in a wavelength band of 670 nm to 690 nm,
• wherein the wavelength with respect to which the infrared light reflector has the 50% transmittance is longer than the wavelength with respect to which the infrared light absorber has the 50% transmittance, and
• wherein a combination of the infrared light absorber and the infrared light reflector provides a light transmission property of 50% transmittance with respect to a wavelength in the wavelength band of 620 nm to 670 nm and less than 5% transmittance with respect to a wavelength of 700 nm.
