OPTICAL FILTER, METHOD FOR PRODUCING SAME, AND IMAGE CAPTURING DEVICE

摘要

Provided is an optical filter comprising an optical filter main body arranged between an image capturing element and a subject or a light source and allowing the transmission of incident light, and a light-blocking resin film integrally formed on at least one surface of the optical filter main body to block a part of light incident to the image capturing element. A fine concavo-convex structure to prevent the reflection of light is formed on the light incident surface of the light-blocking resin film.
