By setting the isolation system between the foundation of the house and the foundation ground, it makes it possible to scale back the influence of the earthquake. A sliding isolator, which is compact and has stable isolation characteristics, had been developed. It was made of a plate with multi convex cell and a sliding plate. This system is a sliding isolator with multipoint contact. The static tests, the shaking table tests and analysis were conducted to confirm the damping capacity of the sliding device. In the element tests, the coefficient of static and dynamic friction and the change in the friction of the total system resulting from construction error were investigated. Movement of the base-isolated house and twisting of the base-isolated house with eccentric load under the actual earthquake loading were surveyed in the shaking table tests. As a result, it was effective and had a stable performance.
