Abstract
An optical sensor module has a light receiver and a light-emitter which is surrounded by a light blocking wall, wherein the light receiver is disposed on a main plate and the light-emitter is disposed on a side plate separately from the main plate. The light blocking wall is formed as a light barrier wall between the light receiver and the light-emitter. A projecting portion projecting upward from the main plate is enclosed by the light barrier wall, and a top face of the projecting portion is higher than the light receiving face and the light-emitting face.
