Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a vibration-damping structure body which eliminates the possibility of the occurrence of blocking during preservation, allows easy wrapping work, is small in the repulsive force after wrapping, is excellent in heat resistance and may not be elongated or dropped even at a high temp. and a rubber compsn. for vibration damping adequately used for the structural body. SOLUTION: This structural body consists of a vibration-damping rubber sheet having self-tacky adhesiveness and a plastic film 3 stuck to the surface layer part of the vibration-damping rubber sheet 1. A plurality of lines of grooves 2 are formed on the surface layer part side. The rubber compsn. is formed by adding 40 to 150 pts.wt. diene rubber having a Mooney viscosity of 20 to 50 at 100 deg.C, 10 to 100 pts.wt. polybutene having a viscosity of 10 to 10 component at 20 deg.C, 1 to 5 pts.wt. vulcanizer and 500 to 900 pts.wt. inorg. filler.
