PURPOSE: To improve the resolution by providing optical means for shifting a light incident region to a photodiode disposed in the same vertical column by a half pitch horizontally between adjacent horizontal rows.

CONSTITUTION: Photodiodes(PD) 6 are arranged at a predetermined intervals such that the centers thereof are aligned in straight lines horizontally and vertically, and vertical transfer CCDs (V-CCDs) 3 are arranged among the PDs 6 in the form of a straight line vertically. Further, a lens 1 is disposed on the upper surface of a planarizing film 9. Further, an Al optical shielding film 4 is disposed on a BPSG film 10. A vertical surface of the lens 1 is directed to oppose the center of the PD 6, and the Al optical shielding film 4 is disposed to cover part of the PD 6 located on the opposite side of the lens 1 from a portion just below the vertical surface of the lens 1 and further cover the V-CCD 3 located likewise on the opposite side of the lens 1 to which signal charges are sent likewise from the opposite side PD 6. The arrangement is repeated up and down and frontally and backwardly in a two-dimensional space.
