NOVELTY - A light-emitting device is obtained by covering a light-emitting element (1) with a curable resin composition, and heating the light-emitting element. The curable resin composition comprises a siloxane type polymer (100 parts mass) obtained from a silane compound, metal oxide particles (50-2000 parts mass), and an organic solvent. The siloxane polymer has a silanol group. The number of hydroxyl groups contained in the silanol group is 15-300% with respect to the number of silicon atoms in the polymer.    USE - Manufacture of light-emitting device (claimed) e.g. LEDs, semiconductor lasers, photodiodes, phototransistors, electroluminescent devices, charge coupled devices, complementary metal oxide semiconductors, and solar cells. The curable resin composition can also be used for antireflective films of optical components and solar cells.    ADVANTAGE - The method uses a curable resin composition having high refractive index, and excellent transparency, crack resistance, weather resistance, light resistance, and heat resistance. The method provides light-emitting device having excellent luminous efficiency.    DETAILED DESCRIPTION - A light-emitting device is obtained by covering a light-emitting element with a curable resin composition, and heating the light-emitting element. The curable resin composition comprises a siloxane type polymer (100 parts mass) obtained from a silane compound of formula: (R1)pSi(X)4-p, metal oxide particles (50-2000 parts mass), and an organic solvent. The siloxane polymer has a silanol group. The number of hydroxyl groups contained in the silanol group is 15-300% with respect to the number of silicon atoms in the polymer.    R1=1-12C non-hydrolyzable organic group;    X=hydrolyzable group;and    p=0-3.    INDEPENDENT CLAIMS are included for the following:    (1) curable resin composition; and    (2) manufacture of curable resin composition, which involves mixing siloxane type polymer and metal oxide particles in an organic solvent.
