Abstract
A solid-state image pickup apparatus includes a light receiving pixel group having light receiving pixels to convert photoelectrically incident light and to be two-dimensionally arranged; a microlens array to be two-dimensionally arranged to correspond in position to the light receiving pixels; a transparent member to be arranged on a light entering side of the microlens array; and a protrusion to support the transparent member, wherein the protrusion is higher than the microlens array and is formed to be integrated with the microlens array.
