PURPOSE: To provide a sold-state imaging device which has no inconvenience such as variations in color and intercolor breeding between adjacent pixels. CONSTITUTION: A metal interconnection layer 2, a plurality of metal plugs 3, metal interconnection layer 4, a plurality of metal plugs 5, metal interconnection layer 6, a plurality of metal plugs 7, and metal interconnection layer 8 are so formed as to enclose a space located vertically on a principal plane of a semiconductor substrate 10 of a photoelectric transfer element 1. These metal sections constitute an optical waveguide, which prevents the leakage of incident light into other photoelectric transfer elements by reflecting the incident light from outside.
