A sliding seismic isolation device includes a structure fixation plate having a first sliding surface and a metallic slider having a second sliding surface contacting the first sliding surface. A friction member composed of a single-layer fabric is attached to the first sliding surface, the second sliding surface, or both of the first sliding surface and the second sliding surface. One of a warp and a weft is formed of multiple plied yarns into which high-strength fibers and PTFE fibers are twisted together and the other of the warp and the weft is formed of multiple high-strength fibers in the single-layer fabric. The single-layer fabric has a twill weave and is woven such that the plied yarns of the one forming the single-layer fabric are exposed at a surface opposite from the attachment side of the friction member more than the high-strength fibers of the other forming the single-layer fabric.
