The photoelectric switch includes: a first light projecting unit; a second light projecting unit a light receiving unit for receiving a reflected light from the first detection area to generate a first light reception signal, and receiving a reflected light from the second detection area to generate a second light reception signal; a casing accommodating the first light projecting unit, the second light projecting unit, and the light receiving unit; and a detection signal generating unit for generating a detection signal based on at least one of the specific wavelength components of the first light reception signal and the second light reception signal.
