A semiconductor light-emitting element 10 includes a silicon single crystal substrate 20 having a first and a second surfaces 20a, 20b in head-tail relationship with each other, a GaN-based semiconductor laminate 40 formed on a selected region of the first surface with a predetermined conductive intermediate layer 25 interposed therebetween, a first electrode layer 51 having a portion in contact with an uppermost layer of the GaN-based semiconductor laminate 40 and insulated from the monocrystal silicon substrate, and a second electrode layer 52 formed on a suitable portion of the monocrystal silicon substrate. The monocrystal silicon substrate 20 is formed with a light guide 30 for directing light emitted from the GaN-based semiconductor laminate 40 toward the second surface 20b.
