To provide a seismic isolation apparatus which, as well as widening an applicable shaking range, can be easily configured and is low in height, a seismic isolation apparatus is configured of a low friction combination formed by a point contact between a planar hard base plate, which has a surface on which are disposed at least three convexly curved projections of a uniform height, and a glide plate which is a smooth, hard, flat plate.
