Patent ID: 8877849

Claim:
A thermosetting resin composition for a reflector of LED, comprising: (A) 100 parts by mass of a thermosetting resin; (B) 3 to 200 parts by mass of white pigment selected from the group consisting of titanium oxide, zinc oxide, zirconium oxide, magnesium oxide, barium carbonate, magnesium silicate, zinc sulfate, and barium sulfate; and (C) 200 to 1300 parts by mass of an inorganic filler other than the component (B), which contains at least the following component (C-1) and the following component (C-2): (C-1) 100 to 1000 parts by mass of at least one kind of inorganic filler that has an average particle diameter of 30 μm to 100 μm and a refraction index that is different from a refraction index of a cured material of the thermosetting resin of the component (A) by 0.05 or more; and (C-2) 100 to 800 parts by mass of at least one kind of inorganic filler that has an average particle diameter of less than 30 μm.
