Abstract
An imaging device in which noise can be reduced, and an electronic device using this device. The imaging device includes a light receiving element, and a read circuit. A field effect transistor in the read circuit has a semiconductor layer in which a channel is formed, a gate electrode that covers the semiconductor layer, and a gate insulating film disposed between the semiconductor layer and the gate electrode. The semiconductor layer has a main surface, and a first side surface on one end side of the main surface in a gate width direction of the field effect transistor. The gate electrode has a first portion that faces the main surface via the gate insulating film, and a second portion that faces the first side surface via the gate insulating film. A crystal plane of the first side surface is a plane or a plane equivalent to the plane.
