A light wavefront measurement device includes a lens array, a light receiving sensor, and a wavefront shape calculation part. The lens array focuses measurement light for each region of the wavefront of the measurement light. The light receiving sensor receives multiple light spots focused by the lens array to output an electrical signal for pixels where the amount of received light has changed.
