ABSTRACT:
An apparatus for firmly mounting solid-state image sensors to an image splitting prism in which a mounting glass block is bonded to an image splitting prism surface or to a glass plate bonded to a prism. A metal film is formed on the glass block, and a preliminary solder layer is formed on the metal film to improve wettability. A gap between the preliminary solder layer and a meltable metal member formed on a caging of a solid-state image sensor is filled with a meltable metal having a predetermined thickness, thus bonding the preliminary solder layer and the meltable metal member. When this construction can be obtained, the total thickness of the metal film can be reduced to 1 .mu.m or less.
