PROBLEM TO BE SOLVED: To provide a base isolation rubber laminated body capable of improving degree of freedom in design by bringing deformation characteristic for tensile force close to deformation characteristic after yielding of solid rubber. SOLUTION: In this base isolation rubber laminated body 1 constituted by laminating a plurality of rubber layers 2 and steel plates 3 alternately in the vertical direction, a plurality of cavities 4 are arranged by dispersing them in the inside of at least one layer among the rubber layers 2.
