Claim:
1. A method of manufacture of a light-emitting diode comprising a substrate upon which are sequentially provided a reflecting layer, a transparent film wherein multiple ohmic contact electrodes are embedded at intervals, and a compound semiconductor layer sequentially including a current diffusion layer and a light-emitting layer, which comprises the following steps in this order: a step of forming a compound semiconductor layer that includes a light-emitting layer and a current diffusion layer on a growth substrate in this order; a step of forming multiple ohmic contact electrodes that are disposed at intervals on said current diffusion layer, wherein said ohmic contact electrodes are cylindrical members having a diameter of about 5 to 20 μm; a step of forming a transparent film having a film thickness of 0.05 to 1.00 μm on said current diffusion layer so as to cover a periphery of the surface facing the substrate of each of said multiple ohmic contact electrodes and so as to expose a part of the surface except for the covered periphery; a step of forming a reflecting layer on said transparent film, and on the exposed portions of said ohmic contact electrodes; a step of forming a bonding layer on said reflecting layer; a step of bonding a substrate to said bonding layer; and a step of removing said growth substrate, wherein current diffusion layer is composed of any one of GaP, {Al
