Abstract

A resin composition which includes: (A) a polyorganosiloxane that contains a mercaptoalkyl group bonded to a silicon atom and has a viscosity at 23° C. of 20 to 3,000 cP; (B) a polyorganosiloxane containing an aliphatic unsaturated group; (C) a photoreaction initiator; (D) a chemically surface-treated silica having a BET specific surface area of 50 to 250 m/g and a pH of 5.0 to 9.0; and (E) a polyoxyalkylene glycol, and/or a derivative of the polyoxyalkylene glycol. (B) includes: a linear polyorganosiloxane; and optionally a branched polyorganosiloxane. The ratio of mercaptoalkyl groups in (A) to the total aliphatic unsaturated groups in (B) is 0.45 to 2.00, the content of (D) is 0.5 to 26 parts relative to 100 parts by mass of (B), the content of (E) is 0.001 to 1.0 mass % relative to the total mass of (A) to (E), and the viscosity at 23° C. is 500 to 100,000 cP.
