Abstract: The invention provides a vibration-absorbing silicone gel composition mainly comprising: 100 parts by weight of (a) an organopolysiloxane having a (meth)acryloyl group in its molecule; from 5 to 100 parts by weight of (b) an organopolysiloxane unreactive with ingredient (a); from 1 to 50 parts by weight of (c) an amorphous pulverization product of a three-dimensionally crosslinked silicone resin; from 1 to 20 parts by weight of (d) a fumed silica; and an effective amount of (e) a polymerization initiator, as a gel composition which has high vibration-absorbing properties and high shape retention and which can be used as, e.g., a vibration-absorbing damper even when it is not sealed up in a container or bag.
