<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a substrate with a reflector having a reflector having tapered surfaces without causing a warp of a lead frame. <P>SOLUTION: One or a plurality of through-holes for forming cavities are formed by punching a sheet-like resin which is a precursor of reflectors, heating members having tapered surfaces are inserted into these through-holes while being heated, inner wall surfaces of the through- holes are expanded while being fused, to form the tapered surfaces expanding toward the light output side of luminescent elements in the inner wall surfaces of the through-holes, and the sheet-like resin having the through-holes with the tapered surfaces formed in the inner wall surfaces is adhered onto lead frames, thereby manufacturing a substrate with the reflector. <P>COPYRIGHT: (C)2013,JPO&INPIT |
