The reinforcing base being composed of a woven fabric formed by using, respectively as the warp and the weft, a ply yarn which is formed by paralleling at least two strands of a single twist yarn spun from fluorine-containing resin fiber and a single twist yarn spun from polyester fiber, and by twisting them in the direction opposite to the direction in which the single twist yarns were spun. Additionally, a multi-layered sliding contact component having the overall shape of a flat plate or a circular cylinder includes the above-described sliding contact surface-forming material so as to configure at least the sliding-contact surface thereof.
