Abstract

Provided is: a curing reactive silicone composition having sufficient toughness and pressure sensitive adhesive strength to temporarily secure various substrate even in an uncured state, having heat meltability and excellent moldability of a sheet or the like, and that can be quickly cured by high energy irradiation to achieve high adhesive strength; a method of manufacturing a sheet thereof a cured product thereof that can achieve high adhesive strength by crimping; and applications thereof. The curing reactive silicone composition comprises: (A) an MQ resin; (B) a chain organopolysiloxane having at least two groups containing an aliphatic unsaturated carbon-carbon bond, and a degree of siloxane polymerization within a range of 80 to 3000; (C) an organohydrogenpolysiloxane; and (D) a hydrosilylation reaction catalyst activated by a high energy beam. The amount of component (A) is more than 55 mass % and less than 90 mass % of the sum of components (A) to (C).
