Imaging device and electronic equipment

An electronic apparatus comprising an imaging device that includes:

• a first substrate in which a pixel array portion composed of pixels that include light receiving portions and are arranged in a matrix is formed;
• and
• a second substrate in which a pixel control portion that controls the pixels is formed and on which the first substrate is stacked, wherein
• the first substrate includes
• a first wiring line configured to transmit a first voltage,
• a second wiring line configured to transmit a second voltage, and
• a fault detection circuit configured to, when the pixel array portion is divided into a plurality of pixel blocks each corresponding to a plurality of pixel columns or a plurality of pixel rows, perform detection of a wiring fault for each pixel block, and
• the fault detection circuit is configured to
• during time for detecting a wiring fault, connect a plurality of wiring lines corresponding to a plurality of pixel columns or a plurality of pixel rows in series in each pixel block, connect one of ends of a wiring chain connected in series in each pixel block to the first, wiring line, connect the other end to the second wiring line, and
• detect a wiring fault based on a potential at an intermediate position of the wiring chain.
