Abstract
An aspect of the present invention allows for determining a cause of abnormality in output of a light-receiving element among light-receiving elements in a multiple optical-axis photoelectric sensor. A multiple optical-axis photoelectric sensor () determines that electrical noise occurs, in a case where abnormality in output occurs in both of adjacent light-receivable periods (Ts) in one light-receiving cycle (Tc).
