1. A gel-forming silicone composition comprising:

  • (A) an organopolysiloxane containing a silicon-bonded vinyl group in an average amount of from 0.15 to 0.35 mol % based on the amount of all the silicon-bonded organic groups contained in its molecule;

    (B) from 10 to 150 parts by weight per 100 parts by weight of the component (A), a non-functional organopolysiloxane other than (C) having the following average composition formula (2);

    
    
    space="preserve" listing-type="equation">(R.sup.3).sub.c Sio.sub.(4-c)/2 (

         2) wherein R3 is a substituted or unsubstituted non-functional monovalent hydrocarbon group, and c has a value of from 2.0 to 2.2, component (B) having a viscosity at 25°

    C. not higher than the viscosity at 25°

    C. of the component (A);

    (C) an organohydrogenpolysiloxane containing an average of from 1 to 3 silicon-bonded hydrogen atoms per molecule present in an amount such that the amount of the silicon-bonded hydrogen atoms in the component (C) is from 0.8 to 2.0 moles per mole of the vinyl groups in the component (A); and

    (D) an addition reaction catalyst.
