An infrared cut filter includes: a transparent dielectric substrate; an infrared reflecting layer formed on one surface of the transparent dielectric substrate and configured to reflect infrared light; and an infrared absorbing layer formed on the other surface of the transparent dielectric substrate and configured to absorb infrared light. The infrared absorbing layer is formed by encapsulating infrared absorbing pigment in a matrix containing silica, formed by a sol-gel method, as a main component.
