Abstract
A motion sensor comprises: a plurality of first light emitting elements, which emit lights having mutually different characteristics in the region of movement of the object to be detected; a light receiving element, which receives reflected light that is emitted from the first light emitting elements and reflected by the object to be detected; a second light emitting element, which emits light towards the light receiving element; and a separation member. A light guiding part, which guides light emitted from the second light emitting element so as directly irradiate the light receiving element, without passing through the region of movement of the object to be detected, and light blocking parts, which block light so that light from the first light emitting elements does not directly irradiate the light receiving element, are formed integrally with the separation member.
