A photoelectric sensor includes a current division control circuit that sequentially sets a reference voltage for each current divider circuit along one of the arrangement directions of photodiodes so that the reference voltage for the current divider circuit is equal to or larger than the voltage value of the reference voltage set for a current divider circuit in the preceding stage, and sets one common control voltage for all of the current divider circuits, the common control voltage falling within a range that includes all of the reference voltages. |
