ABSTRACT:
A method for producing a resin-sealed photoelectric converting device which eliminates the problem of uneven resin refractive index produced when the resin is injected past the lead wires and over the light receiving elements. The photoelectric converting device has a photoelectric converting element, and wires for electrically connecting electrodes of the photoelectric converting element with lead electrodes. A transparent portion is present on the light receiving portion of the photoelectric converting element. The method includes the steps of placing the photoelectric converting element and the lead electrodes in a mold cavity having a resin-injecting gate; and injecting resin from the gate and guiding the injected resin which bypasses said wires to an area away from the photoelectric converting portion, and sealing the entire photoelectric converting element with the injected resin. Since the resin which bypasses the wires does not cover the light receiving portion, any unevenness in the resin will not produce an uneven refractive index over the light receiving portion.
