Provided is a multi-optical axis photoelectric sensor that can achieve downsizing and weight reduction. The multi-optical axis photoelectric sensor includes a case body which is formed to have open ends and has the same cross-sectional shape in a longitudinal direction of the multi-optical axis photoelectric sensor; end members which are attached to one end and the other end of the case body and each formed of a molded article for closing an opening on each of the ends; and an optical component which is arranged from one end to the other end of the case body so as to be separated from an inner face of the case body. The optical component has a function of defining the spread angle of each optical axes. The optical component and the end members are directly or indirectly physically engaged with each other to unrotatably position the optical component by the end members. |
