Abstract
A solid-state image sensor includes pixels, each of which is provided with a light receiving portion, a charge storage portion, a gate electrode, a first trench formed in a region between the light receiving portion and the charge storage portion, a first insulating film provided in the first trench, a transmitting portion, and a light-shielding film covering the charge storage portion, the transmitting portion, and the gate electrode. In a plan view, a distance from an end of the light-shielding film through the transmitting portion to the charge storage portion in a direction from the light receiving portion toward the charge storage portion is longer than a distance from the end of the light-shielding film through the first trench to the charge storage portion.
