An optical filter that is disposed in front of an image sensor. The optical filter includes a first optical member, and a second optical member that is disposed closer to the image sensor than the first optical member. An anti-reflection multilayer film is formed on an incident surface of the first optical member. A film which is made of a material containing fluorine is formed on an outermost layer of the anti-reflection multilayer film. A dichroic multilayer film is formed between a light-emitting surface of the first optical member and an incident surface of the second optical member. |
