The surface and the rear surface of the samples are moved to opposite directions. A shear strain deformation is generated in the samples as rubberlike elastic bodies. The deformation degree of the rubberlike elastic bodies is measured on the basis of the reference marks 15. Then, when a rubber physical property value in a rubber part 11a in the central part at a distance from their bonding interface is found, the physical property value of the rubber part 11b near the bonding interface can be calculated and estimated on the basis of the ratio of the part to a strain.
