Abstract

The present invention relates to a photocurable silicone gel composition includes: (A) an organopolysiloxane having at least one group represented by the following general formula (1): in which R¹ and R² each represent hydrogen or an alkyl group having a carbon number of 1 to 20, in an amount of 100 parts by mass; (B) a mercaptoalkyl group-containing organopolysiloxane in an amount of parts by mass such that the number of moles of the mercaptoalkyl group is 0.01 to 1.0 mole per 1 mole of the group represented by the general formula (1) in the component (A); (C) a photopolymerization initiator in an amount of 0.01 to 20 parts by mass per 100 parts by mass of the component (A); and (D) a hindered amine compound having a group represented by the following general formula (2): in which R³ to R⁶ each represent hydrogen or an alkyl group having a carbon number of 1 to 20, and R⁷ represents hydrogen or —CH₂—R⁸ in which R⁸ represents hydrogen or a monovalent organic group, in an amount of 0.001 to 10 parts by mass per 100 parts by mass of the component (A):
