Abstract
An imaging device according to an embodiment of the present disclosure includes: a first substrate including, in a first semiconductor substrate, a sensor pixel that performs photoelectric conversion; a second substrate including, in a second semiconductor substrate, a readout circuit that outputs a pixel signal based on charges outputted from the sensor pixel, in which the second substrate is stacked on the first substrate; and a first hydrogen diffusion prevention layer provided between the first semiconductor substrate and the second semiconductor substrate.
