The present invention provides a compact camera head for a solid-state image pickup device, a dimension of which is not so limited by a package for a solid-state image pickup element. Outer-leads are connected via inner-leads respectively to electrodes of a solid-state image pickup chip to constitute the solid-state image pickup element. An optical glass plate is attached to a light-receiving surface of the solid-state image pickup chip. The outer-leads are connected to side electrodes of a circuit module constituted by a chip-connecting board, a circuit board and a connector board, to thereby provide an image pickup unit. The image pickup unit is inserted into a chassis, and the opposite open ends of the chassis are sealed by an optical filter and a seal plate.
