Claim Text:
1. A thermosetting resin composition for light reflection, comprising a thermosetting component and a white pigment (E), wherein: the thermosetting resin composition has a property of light reflectance at a wavelength of 350 nm to 800 nm, after thermal curing, which is not lower than 80%, and wherein: the thermosetting component contains an epoxy resin (A) and a curing agent (B) containing an acid anhydride; said white pigment (E) includes a mixture of inorganic hollow particles and at least one selected from the group consisting of alumina, magnesium oxide, antimony oxide, titanium oxide, and zirconium oxide; and wherein the inorganic hollow particles are made of at least one selected from the group consisting of sodium silicate glass, aluminosilicate glass, sodium borosilicate soda glass and Shirasu glass; the thermosetting resin composition comprises a kneaded product obtained under a condition where constituent components are kneaded at a kneading temperature of 20 to 100° C. for a kneading time of 10 to 30 minutes; and said kneaded product is aged at 0 to 30° C. for 1 to 72 hours after the kneading.
