Claim Text:
1. A curable composition that comprises: (A) a polymerized product comprising a linear organosiloxane compound, which is represented by an average composition formula of Formula 1 and, of which a molar ratio of an alkenyl group bound to a silicon atom with respect to the total silicon atoms ranges from 0.02 to 0.2; (B) a crosslinked organosiloxane compound, which is represented by an average composition formula of Formula 2, and of which a molar ratio of an alkenyl group bound to a silicon atom with respect to the total silicon atoms ranges from 0.15 to 0.35; and (C) a hydrogen siloxane compound, which is represented by Formula 3, and of which a molar ratio of a hydrogen atom bound to a silicon atom with respect to the total silicon atoms ranges from 0.2 to 0.8, the crosslinked organosiloxane compound being comprised in a weight ratio of 50 parts by weight to 700 parts by weight relative to 100 parts by weight of the linear organosiloxane compound, a molar ratio of a hydrogen atom bound to a silicon atom in the siloxane compound with respect to an alkenyl group bound to a silicon atom in the linear and crosslinked organosiloxane compounds ranging from 0.8 to 1.2 and the hydrogen siloxane compound comprising an aryl group in such an amount that a molar ratio (Ar/Si) of the aryl group (Ar) with respect to the total silicon atoms (Si) in the hydrogen siloxane compound is in a range from 0.4 to 0.8: wherein R
