1. An imaging element, comprising:
a pixel board including a light receiver arranged on the pixel board, the light receiver including plural pixels that are arranged in a two-dimensional matrix, each pixel being configured to receive light from an outside of the pixel and generate an imaging signal according to quantity of the light received;
a circuit board including a functional circuit with a predetermined function, the pixel board being layered on the circuit board;
plural wiring portions configured to electrically connect the pixel board and the circuit board to each other and electrically transmit signals between respective layers;
a terminal provided on the circuit board, the terminal being electrically connected to each of the plural wiring portions, the terminal being configured to output the imaging signal to an outside of the terminal or receive an external signal from the outside of the terminal; and
a switch configured to output, by selective switching, at least one of the imaging signal and an internal signal generated at the circuit board, to the terminal.
