PURPOSE:To obtain a small-sized, light-weight, and very inexpensive solid-state image pickup camera by arranging a lens, which has an approximately spherical convex at least as one face, in front of a CCD element whose light receiving face is 3mm square or smaller and setting the diameter of an aperture to <=1.0mm. CONSTITUTION:A lens 1 which has an approximately spherical convex at least as one face is arranged in front of a CCD 7, whose light receiving face 8 is 3mm square or smaller, so that the convex faces the light receiving face 8, and the diameter of an aperture 10 is set to <=1.0mm. Since the chip size of the CCD is very reduced, the yield per unit wafer is increased and the CCD unit price is considerably reduced. Since the aperture is reduced to <=1.0mm with respect to the micro lens corresponding to the micro CCD, the fixed focus system can be adopted and an image of less distortion is obtained.
