IMAGING DEVICE

原文（中文）

An imaging device includes a photoelectric converter, a first active element, and a first semiconductor layer. The photoelectric converter generates electric charge. The first active element performs a predetermined operation on the electric charge generated by the photoelectric converter, and includes a gate electrode including a first electrode part, a second electrode part, and a third electrode part. The first electrode part and the second electrode part are provided side by side in a first direction. The third electrode part couples the first electrode part and the second electrode part to each other. The first semiconductor layer includes a first surface and a second surface, has the first electrode part and the second electrode part of the gate electrode embedded in the first semiconductor layer on a side of the first surface, and includes a first semiconductor region between the first electrode part and the second electrode part.
