Abstract
An optical biosensor module includes a circuit board having a mounting surface and first and second circuits. A light-receiving unit is disposed on the mounting surface, and includes a light receiver electrically connected to the first circuit and having a light-receiving surface. A light-emitting unit is disposed on the light-receiving surface, and includes a light emitter electrically connected to the second circuit and having a light-emitting surface, and a light emitter blocking wall surrounding the light emitter. An opaque interface exists between the light receiver and the light emitter, and a top side of the light emitter blocking wall is equal to or higher than the light-emitting surface.
