Zusammenfassung:	A solid-state image sensor having a plurality of unit cells, each of which comprises a photosensitive area (24, 25) and a CCD register (23) for the transfer of a signal charge generated in said photosensitive area (24, 25), wherein both said photosensitive area (24, 25) and said CCD register (23) are disposed on a first layer (22), having a different polarity from the charging polarity of said signal charge, which is disposed on a substrate (21) having the same polarity as said signal charge, said CCD register (23) being underlaid by a second layer (33) having the same polarity as the first layer (22) and containing the impurity in a higher concentration than that of the first layer (22).
