ABSTRACT:
This invention can suppress adhesion of dust to the surface of an optical filter and the cover glass surface of a solid-state image sensor without any optically adverse effect. An image capturing apparatus includes an image capturing device which converts the optical image of an object into an electrical signal, and an optical element (11) arranged in front of the image capturing device. Minute particles of a single layer (11a) are arrayed on a surface of the optical element on the object side.
