The objective of the present invention is to provide a photoelectric sensor which enables to visualize lighting of an indicating lamp easily. The photoelectric sensor comprises a case accommodating: a light transmitting device and a light receiving device detecting object to be detected; a circuit board (6) mounted with a control circuit which outputs a detection signal when detecting the object to be detected based on motion of the light transmitting device and the light receiving device; and an indicating lamp (25) provided on a mounting surface of a circuit device of the circuit board. On a top surface of the case, the light transmitting device and the light receiving device are installed, extending upward, facing each other, and having a preset interval therebetween. The sensor comprises a substrate cover (19) which is exposed to a surface of the case and at the same time covers the mounting surface of a circuit device and transmits visible light outputted from the indicating lamp (25), a space secured between the substrate cover and the mounting surface (24) of a circuit device, and a scattered light generation unit (23) which is provided in the substrate cover and scatters the visible light. |
