Zusammenfassung:	The fibrous laminate includes fibrous layer I composed of ultrafine fibers having a mean fiber diameter of 10 to 1,000 nm and fibrous layer II composed of thermo-fusible conjugate fibers having a mean fiber diameter of 5 to 100 μm, in which contact points between the ultrafine fibers and the thermo-fusible conjugate fibers are bonded by melting of the thermo-fusible conjugate fibers composing the fibrous layer II, and the fibrous layer I and the fibrous layer II are laminated and united by the formed bonding points.
