Claim 0:
1. An imaging device comprising:
a pixel electrode;
a counter electrode that faces the pixel electrode;
a first photoelectric conversion layer that is located between the pixel electrode and the counter electrode and that generates first signal charge;
a second photoelectric conversion layer that is located between the first photoelectric conversion layer and the pixel electrode and that generates second signal charge;
a first barrier layer that is located between the first photoelectric conversion layer and the second photoelectric conversion layer and that forms a first heterojunction barrier against the first signal charge in the first photoelectric conversion layer; and
a charge accumulator that is electrically connected to the pixel electrode and that accumulates the first signal charge and the second signal charge.
