Abstract
Abstract An imaging device having solid-state image sensors coupled to a prism for separating the light from an objective optical system, wherein a solder layer capable of adhering to a glass substance is formed on a part of said prism or on a glass plate adhered to said prism, and a gap between said solder layer and a solderable material formed on a casing of said solid-state image sensor is filled with a low-melting metal to unite the two. The metal layer thickness of the solder layer is disposed to cause the light receiving surface of the image sensor to correspond to a predetermined imaging plane of the imaging device.
