The invention provides a rubber composition comprising a styrene-butadiene copolymer and having improved compatibility with a thiol-based crosslinking agent and also having increased curability. As means for solving the problems, the inventive thiol-containing liquid rubber composition comprises (A) a styrene-butadiene copolymer which is liquid at 25° C. and (B) a polythiol derived from mercaptocarboxylic acid, wherein the styrene-butadiene copolymer (A) desirably has a bound styrene content of 20 to 90% by mass.
