PROBLEM TO BE SOLVED: To prevent level difference shield effects reducing the substantial sensitivity of a pixel right below the level difference in such a manner that thinned chips are slid bit by bit and overlapped, a pixel array is formed on the elongate surface exposed by being slid, two pairs of terrace-paddy-field like image pickup elements, in which a high intelligence circuit is incorporated to a large part of the area covered by the upper chips, are opposite arranged, by this, a boundary at the level difference part on a reproduced image caused by the deviation of the focus caused by the level difference is substantially erased, and at the same time, the light to enter the pixel right below the level difference is shielded by the level difference. SOLUTION: Each pair is respectively arranged slightly slantingly to the optical axis so that a line connecting the middle point of the pixel array of each chip 101 exposed by being slid is aligned with an image forming face 110.
