The nonwoven fabric includes at least two types of fibers having different melting points, which fibers are low melting point fibers made of a polyolefin resin component A, and high melting point fibers made of a high melting point resin component B having a higher melting point than that of the polyolefin resin component A. The number average fiber diameter of the high melting point fibers is larger than that of the low melting point fibers. At least one high melting point fiber having a fiber diameter of 20 μm to 100 μm is present per 1.00 mm of the length of the cross section of the nonwoven fabric. The number average fiber diameter of all fibers constituting the nonwoven fabric falls within the range of 0.3 μm to 10 μm.
