Abstract
In an image capture apparatus, the surface of an optical element and a shutter are made to have conductivity, and they are grounded so as to have the same potential, so that adhesion of foreign matter onto the surface of the optical element can be prevented.
Claims7

- a shutter blade having electrical conductivity;
- and
- an optical element located behind the shutter blade as viewed from a lens unit,
- wherein an electrical potential of at least a surface facing an object side of the optical element is the same as an electrical potential of the shutter blade.
