Abstract
An imaging device having a superior light-shielding property for a charge-holding section is provided. The imaging device includes: an Si {111} substrate extending along a horizontal plane; a photoelectric conversion section provided in the Si {111} substrate and generating charges corresponding to a light reception amount by photoelectric conversion; a charge-holding section provided in the Si {111} substrate and holding charges transferred from the photoelectric conversion section; and a light-shielding section including a horizontal light-shielding part positioned between the photoelectric conversion section and the charge-holding section in a thickness direction and extending along the horizontal plane and a vertical light-shielding part orthogonal thereto. The horizontal light-shielding section includes a first plane along a first crystal plane of the Si {111} substrate of a plane index {111} orthogonal to the thickness direction, and a second plane along a second crystal plane of the Si {111} substrate inclined to the thickness direction.
