Abstract

An image sensor includes: a pixel chip provided with a plurality of pixels, a plurality of first transfer lines, and a plurality of capacitors; a circuit chip provided with a plurality of column reading circuits, a plurality of column scanning circuits, a second transfer line, and a constant current source; and a connection portion stacked and provided between the pixel chip and the circuit chip and configured to connect a capacitor, which is arranged in the pixel chip and has a trench structure, and a first transistor arranged in the circuit chip to each other via an electrode. The capacitor is configured to form a transfer capacity removing a noise included in an imaging signal and connect the pixel chip and the circuit chip to each other via the electrode and the connection portion.
