<P>PROBLEM TO BE SOLVED: To provide a method for improving rubber performance, in blending a filler such as carbon with a diene-based rubber, by enhancing bonding of the rubber with a reinforcing material and a crosslinked structure of the rubber. Ž<P>SOLUTION: A rubber composition comprises the diene-based rubber, the filler such as carbon, and a compound expressed by general formula (I) [wherein: R<SB>1</SB>comprises a divalent or trivalent alkylene or oxyalkylene group having 2-20 methylene groups; x is an integer of 1-6; n is an integer of 1-50; A has a cyclic amino group represented by general formula (II); R<SB>2</SB>comprises a divalent alkylene or oxyalkylene group having 3-12 methylene groups; R<SB>3</SB>comprises a 1-12C divalent hydrocarbon group or an O-containing divalent hydrocarbon group or R<SB>3</SB>=O, or a tertiary amino group having a structure of general formula (III); R<SB>4</SB>and R<SB>5</SB>comprise a 1-12C alkyl or oxyalkyl group].
