To provide a camera device capable of restraining a reflected light signal generated in the optical part of a camera.
The camera device has a lens array for focusing an incident optical signal, a window glass positioned in front of the lens array and preventing a foreign matter from coming into contact with the lens array, and a barrel for fixing the lenses of the lens array. The respective lenses of the lens array are coated with a multilayer thin film so as to respectively restrain the reflected waves of the incident optical signals having different wavelengths, and the thin film with which the lenses are coated has thickness to make the phase of the reflected wave reflected after it is transmitted through the thin film reverse to the phase of the reflected wave reflected on the surface of the lens.
