Reflecting resin sheet, light emitting diode device and producing method thereof

摘要

A reflecting resin sheet (13) provides a reflecting resin layer (4) at the side of a light emitting diode element (3) and includes a first release substrate (21) and the reflecting resin layer (4) provided on one surface in a thickness direction of the first release substrate. In the first release substrate and the reflecting resin layer, a through hole (9) extending therethrough in the thickness direction is formed corresponding to the light emitting diode element (3) so as to allow an inner circumference surface of the through hole in the reflecting resin layer to be disposed in opposed relation to a side surface of the light emitting diode element.
