Light detecting elements are formed in areas marked off by scribe lines on
a semiconductor substrate, and color filters are deposited in such a
manner as to cover the formed areas of the light detecting elements, and
then an infrared cut-off filter, on which an infrared reflecting film is
vapor-deposited in such a manner as to cover the formed areas of the
light detecting elements, is firmly fixed to the surface of the
semiconductor substrate through the interposition of a translucent resin
layer, such as an epoxy adhesive, to thereby form a multilayered
structure, and this multilayered structure is diced along scribe lines.
