Abstract:
1. A resin composition for sealing an optical device, comprising: (i) a silylated organopolysiloxane with a polystyrene equivalent weight average molecular weight of 5×10 (wherein, each R 1 represents, independently, an alkyl group of 1 to 6 carbon atoms, an alkenyl group of 1 to 6 carbon atoms, or an aryl group of 1 to 6 carbon atoms; X represents a combination of a group represented by a formula —SiR 2 R 3 R 4 (wherein, R 2 , R 3 and R 4 each represent, independently, an unsubstituted or substituted monovalent hydrocarbon group), and one or more groups selected from amongst alkyl groups, alkenyl groups, alkoxyalkyl groups and acyl groups of 1 to 6 carbon atoms; a represents a number within a range from 1.00 to 1.5; and a+b satisfies 1.00<a+b<2), and (ii) a condensation catalyst.
