Abstract: The present invention provides a non-woven fabric that: comprises fibers comprising a polyolefin-based resin; and has water resistance, flexibility, and excellent workability. This laminated non-woven fabric has laminated therein a spun-bond non-woven fabric layer and a melt-blow non-woven fabric layer. The spun-bond non-woven fabric layer comprises complex fibers comprising a thermoplastic resin (A1) and a polyethylene-based resin (A2). The thermoplastic resin (A1) is either a polyolefin-based resin (A1a) or a polyester-based resin (A1b). The melt-blow non-woven fabric layer comprises fibers comprising a polyolefin-based resin (B). In addition, the average single fiber diameter of the complex fibers in the spun-bond non-woven fabric layer is 6.5-11.9 µm and the complex viscosity of the spun-bond non-woven fabric layer measured at 230°C and 6.28 rad/sec is no more than 100 Pa·sec.
