A photoelectric converter includes a photoelectric conversion element, which includes a first electrode and a second electrode disposed discretely and a photoelectric conversion material layer disposed between the first electrode and the second electrode and in which a current generated in the photoelectric conversion material layer changes with the lapse of an application time, where a constant amount of light is applied to the photoelectric conversion material layer while a voltage is applied between the first electrode and the second electrode, and a current detection circuit to detect the change in the current.
