Imaging element and electronic device

An electronic device, comprising:

• a plurality of pixel blocks including:
• a semiconductor substrate in which a plurality of pixels and an isolation section that isolates the pixels are arranged, the plurality of pixels each including:
• a photoelectric conversion section that performs photoelectric conversion of incident light;
• and a charge holding section that holds a charge generated by the photoelectric conversion;
• a shared electrode disposed adjacent to the semiconductor substrate and having a shape straddling the isolation section, the shared electrode connected to the charge holding section of each of the plurality of pixels;
• a wiring region disposed adjacent to a front surface side of the semiconductor substrate;
• and a signal generation section that generates a pixel signal that is a signal corresponding to a voltage of the shared electrode;
• a shielding section disposed between the shared electrodes of the plurality of pixel blocks, the shielding section applied with a voltage different from a voltage of the shared electrodes;
• and
• a processing circuit that processes the pixel signal.
