Provided is a curable granular silicone composition which has hot-melt properties, is excellent in terms of handleability and curability in overmolding and the like, and gives cured objects and the like highly inhibited from taking a color at high temperatures. The curable granular silicone composition comprises: (A) organopolysiloxane resin fine particles which do not have hot-melt properties and have a curing-reactive functional group containing a carbon-carbon double bond and in which siloxane units represented by RSiO.sub.3/2 (where R is a monovalent organic group) or SiO.sub.4/2 account for at least 20 mol % of all the siloxane units; (B) a liquid, linear or branched organopolysiloxane having, in the molecule, at least two curing-reactive functional groups containing a carbon-carbon double bond; (C) a hardener; and (D) a functional filler. The composition as a whole has hot-melt properties. Uses of the curable granular silicone composition are also disclosed.
