A bicyclic conjugated diene polymer obtained by polymerizing a monomer (M) comprising at least one kind of bicyclic conjugated diene monomer represented by formula (I), and a bicyclic conjugated diene copolymer obtained by copolymerizing monomer (M) with at least one kind of unsaturated compound other than said monomer: wherein, R<SUB>1 </SUB>to R<SUB>6 </SUB>are the same or different and are each hydrogen, halogen, or alkyl or halogenated alkyl of 1 to 20 carbon; n and m are each an integer of from 0 to 10; X<SUB>1</SUB>, X<SUB>2</SUB>, Y<SUB>1 </SUB>and Y<SUB>2 </SUB>are the same or different from each other and are each hydrogen, halogen or alkyl or halogenated alkyl of 1 to 20 carbon; and, when m or n is 2 or more, each of mX<SUB>1</SUB>'s, mX<SUB>2</SUB>'s, nY<SUB>1</SUB>'s and nY<SUB>2</SUB>'s are the same or different.
