Optical filter and imaging apparatus

An optical filter used for an imaging apparatus having a built-in image sensing device on which light from a subject or a light source is incident, the optical filter comprising:

• an optical filter body arranged between the subject or the light source and the image sensing device, and having a transmission property for the incident light;
• and
• a light shielding film arranged on at least one surface of the optical filter body, having a predetermined pattern shape, and shielding a part of the incident light,
• wherein the optical filter body has a transparent substrate, and a first fine uneven structure suppressing reflection of light is provided on at least one interface between the transparent substrate and the light shielding film.
