1. A photoelectric conversion element comprising:
a first pixel array including first light-receiving sections arranged in a direction,
each of the first light-receiving sections including:
a first pixel configured to receive at least light having a first wavelength inside a visible spectrum; and
a first pixel circuit configured to transmit a signal from the first pixel to a subsequent stage;
a second pixel array including second light-receiving sections arranged in the direction; and
a dummy pixel array configured to imitate a pixel array and a pixel circuit at an end portion of a sensing area including at least the second pixel array, wherein the dummy pixel array is arranged at each end portion of the sensing area,
each of the second light-receiving sections including:
a second pixel configured to receive at least light having a second wavelength outside the visible spectrum; and
a second pixel circuit configured to transmit a signal from the second pixel to the subsequent stage, and
the second pixel circuit provided in an adjacent area of the second pixel.
