PROBLEM TO BE SOLVED: To provide a thermosetting resin composition for light reflection having a high reflective index from visible light to near-ultraviolet light after hardening, and to provide an optical semiconductor mounting substrate using the same and a method of manufacturing the optical semiconductor mounting substrate.SOLUTION: In a thermosetting resin composition for light reflection containing (A) epoxy resin, (B)a hardener, (C) a hardening catalyst, (D) an inorganic filler, (E) a white pigment, and (F) a coupling agent, an optical reflective index at a wavelength of 800-350 nm after thermal hardening is 80% or more, and pressure molding at an ambient temperature (25°C) is possible before thermal hardening. |
