Disclosed are an edge-illuminated refracting-facet type light receiving device and a fabricating method thereof. The edge-illuminated refracting-facet type light receiving device has a semiconductor substrate, a photo-absorption layer formed on the semiconductor substrate, a first window layer entirely formed on an upper surface of the photo-absorption layer, a second window layer formed on an upper surface of the first window layer and having a light incident plane, which is inclined at a predetermined angle with respect to the photo-absorption layer in such a manner that light refracted at the light incident plane is incident into the photo-absorption layer, a first conductive metal layer in contact with the second window layer, and a second conductive metal layer, which is different from the first conductive metal layer, formed at a bottom surface of the semiconductor substrate.
