PROBLEM TO BE SOLVED: To provide a base isolation structure and a method of manufacturing for the base isolation structure adapted to a comparatively small lightweight object with a light load. SOLUTION: The base isolation structure 10 is formed as follows. One thin plate 1 is laid on the bottom of a die 20, and a layer is so formed that a plurality of hard particles 2 is isolatedly placed at intervals on the thin plate 1. When forming a single-layer base isolation structure, the thin plate 1 is placed on the layer. When forming a multilayered base isolation structure, a plurality of layers formed by placing the hard particles 2 on the thin plate 1 are similarly layered on the layer. After the thin plate 1 is placed on the uppermost layer, an uncured liquid elastic body material 3a is filled into the die 20, and then the elastic body material 3 is cured.
