Abstract
An imaging element including a plurality of semiconductor chips which are bonded together is prevented from being damaged. The imaging element includes the plurality of semiconductor chips each including a semiconductor substrate and a wiring region. One of the plurality of semiconductor chips is disposed with a photoelectric conversion unit that performs photoelectric conversion of incident light. Two of the plurality of semiconductor chips each includes a first pad, surfaces of the wiring regions of the two semiconductor chips being bonded together, the first pads being disposed on the respective surfaces of the wiring regions and being joined to each other. At least one of the two semiconductor chips further includes a second pad disposed in the wiring region and an insulating film disposed between the second pad and the surface for bonding, the second pad being formed with a protrusion toward the surface for bonding.
