A mixed fiber spunbonded nonwoven fabric which comprises 90 to 10% by weight of a long fiber of thermoplastic resin (A) that has been hydrophilization-treated and 10 to 90% by weight of a long fiber of thermoplastic elastomer (B) and which has a strength ratio [the ratio of a strength at 20% of an elongation at a maximum strength (elongation at a maximum point) to the maximum strength] in at least one direction of not more than 40% and a bulk density of 0.10 to 0.40 g/cm3. The fabric can exhibit excellent initial hydrophilicity, long-lasting hydrophilicity, liquid dispersibility, liquid transpiration property, moisture permeability, breathability, softness, resistance to fluff, stretchability and touch, and low stickiness, and is suitable for sheets constituting absorbent articles such as sanitary napkins, panty liners, incontinence pads, and disposable diapers. A production method is also provided.
