To sufficiently vulcanize the entire base isolating structure body and to secure sufficient adhesive strength at an interface between a rubber plate and a metal plate or the like.

This base isolating structure body is constituted by providing a laminated part 4 with the rubber plates 2 and the metal plates 3 laminated alternately, and treating the interface between the rubber plate 2 and the metal plate 3 with a vulcanizing adhesive including a halide polymer. A rubber composition with 0.1 pts.wt. to 30 pts.wt. of zinc oxide compounded as an acid acceptor in 100 pts.wt. of base material rubber with natural rubber as a main polymer is used for the rubber plate 2.
