Abstract
A photoelectric sensor module includes a first light emitting element that emits light having a first wavelength, a second light emitting element that emits light having a second wavelength different from the first wavelength, and a light receiving element that receives light emitted from the first light emitting element and reflected by an object and light emitted from the second light emitting element and reflected by the object are mounted on a substrate with linear edges. With respect to a virtual straight line defined on a surface of the substrate, a light emitting portion of the first light emitting element and a light emitting portion of the second light emitting element are line-symmetric, a light receiving portion of the light receiving element is line-symmetric, and a shape of the substrate in plan view is line-symmetric.
