To provide a liquid rubber composition which excels in water resistance (moisture permeation resistance), heat resistance, polar solvent resistance, rubber elasticity, filling properties, tacky adhesion (adhesiveness), and workability (low viscosity), and is crosslinkable at a normal temperature.
The composition at least includes: (A) an ethylene, α-olefin, nonconjugated polyene random copolymer including a structural unit that meets a specific requirement and is led from ethylene, a structural unit led from a 3-20C α-olefin, and a structural unit led from at least one nonconjugated polyene; (B) a hydrosilyl group-containing compound having at least two hydrosilyl groups in one molecule; and (C) at least one resin that has compatibility with the copolymer (A), is chosen from a 6-3,000C α olefin that has a double bond at one terminal or both terminals of the molecular chain, and at least 7C terpene-based resin that has a double bond at the inside or the terminal of the molecular chain, in which the number average molecular weight is at most 2,000.
