THERMOSETTING RESIN COMPOSITION FOR LIGHT REFLECTION, SUBSTRATE FOR MOUNTING OPTICAL SEMICONDUCTOR ELEMENT, METHOD OF MANUFACTURING THE SAME, AND OPTICAL SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a thermosetting resin composition for light reflection which can form a cured product capable of sufficiently reducing light leakage in a substrate for mounting optical semiconductor element, and to provide the substrate for mounting optical semiconductor element using the thermosetting resin composition for light reflection, a method of manufacturing the same, and an optical semiconductor device.SOLUTION: The thermosetting resin composition for light reflection contains: a thermosetting resin containing an epoxy resin; and an inorganic oxide having a refractive index of 1.6-3.0. The blending amount of the inorganic oxide is 70-400 pts.mass based on 100 pts.mass of the thermosetting resin.SELECTED DRAWING: None
