Abstract

The present invention provides a silicone gel composition for use in sealing and filling of electrical and electronic parts, which are characterized by the fact that when said composition is cured, said composition forms a silicone gel in which the loss elastic modulus at a temperature of 25.degree. C. and a shear frequency of 0.1 Hz is 1.0.times.10.sup.2 to 1.0.times.10.sup.4 Pa, and in which the complex elastic modulus is 1.0.times.10.sup.5 Pa or less, and a silicone gel which is characterized by the fact that in a silicone gel which seals or fills electrical or electronic parts, the loss elastic modulus of this silicone gel at a temperature of 25.degree. C. and a shear frequency of 0.1 Hz is 1.0.times.10.sup.2 to 1.0.times.10.sup.4 Pa, and the complex elastic modulus is 1.0.times.10.sup.5 Pa or less.
