A foil bearing is provided, which is simple in structure, has a large load capacity and a large damping capability and can therefore allow a rotary shaft having a large unbalance as compared with the conventional bearing to be driven stably at a high speed. A spindle device utilizing such foil bearing is also provided, which is designed to increase the permissible amount of unbalance and also to have a light-weight feature. Each of the foil bearingsandincludes an elastic memberprepared from a wire net formed by braiding wires, and a thin bearing foilsupported by the elastic memberand defining an elastic bearing surface S. The respective foil bearingandis used at least as a radial bearingin the spindle device including a rotary shafthaving a head mounton which an atomizer head is mounted, and the radial and thrust bearingsandfor rotatably supporting the rotary shaft
