PROBLEM TO BE SOLVED: To provide a method for producing a spunbonded elastic nonwoven fabric excellent in strength, pliability and touch feeling, and having a high elasticity, elongation elastic recovery and uniformity by simple equipment at a low cost, and further to provide a spunbonded elastic nonwoven fabric of a polyamide elastomer. SOLUTION: This method for producing the spunbonded elastic nonwoven fabric comprises regulating the fiber density at a drawing and thinning step at which the fiber density becomes highest so as to be within the range of 2-50 yarns/cm2 in the step for heating, melting and kneading raw materials consisting essentially of a thermoplastic elastomer, extruding and spinning the kneaded raw materials from multiple-row spinneret nozzles, and cooling and thinning the resultant spun yarn.
