The solid-state imaging element is formed on the first main surface of a semiconductor substrate. The electrode pad is formed on the first main surface of the semiconductor substrate. The through-hole electrode is formed to extend through the semiconductor substrate between the first main surface and a second main surface opposite to the electrode pad formed on the first main surface. The light-transmitting substrate is placed on a patterned adhesive to form a hollow on the solid-state imaging element. The thickness of the semiconductor substrate below the hollow when viewed from the light-transmitting substrate is larger than that of the semiconductor substrate below the adhesive.
