Abstract
An image-capturing device includes a lens barrel having therein an optical image-capturing system; a light control blade which opens and closes an optical path of the optical image-capturing system so as to control the amount of light entering the system; and a base body having a transmission hole through which the optical path extends and supporting the light control blade in a movable manner. The light control blade includes a multilayer laminate including a base material composed of a film and serving as a substrate, and at least a metallic layer disposed on the base material; and a light-blocking layer disposed on a first section of the multilayer laminate. A second section of the multilayer laminate not having the light-blocking layer disposed thereon defines a light adjustment filter for adjusting the amount of incident light. The first section having the light-blocking layer defines a light-blocking portion for blocking incident light.
