PROBLEM TO BE SOLVED: To provide an imaging device capable of improving the degree of freedom of layout. An image pickup apparatus is arranged on one surface side of a first substrate portion having a sensor pixel that performs photoelectric conversion and a first substrate portion, and outputs a pixel signal based on a charge output from the sensor pixel. A second substrate portion having a circuit is provided. The second substrate portion is arranged on one surface side of the first semiconductor substrate provided with the first transistor included in the readout circuit and the first semiconductor substrate, and is provided with the second transistor included in the readout circuit. It has two semiconductor substrates. [Selection diagram] Fig. 3 |
