PROBLEM TO BE SOLVED: To provide a multiple optical-axis photoelectronic sensor mountable on a mounting plane by face contact by a simple constitution. SOLUTION: The multiple optical-axis photoelectronic sensor includes lengthy body cases (20A, 20B). In the body backside opposite to its window part 22 for detection, the body cases (20A, 20B) have a form that its backside is off set to the window side for detection by a prescribed amount, and have a notch 26 formed at both ends in the longitudinal direction of the body cases (20A, 20B). When a mounting member 50 having a mounting part 52 in order to mount the main cases (20A, 20B) on a prescribed mounting flat face 72 is mounted on the notch 26, the notch 26 makes the backsides of the body case flush with the mounting member 50, and the body cases (20A, 20B) are brought into surface contact with the mounting flat face 72.
