Provided is a method for producing a long fiber nonwoven fabric which uses polyphenilene sulfide exhibiting excellent spinnability as the main component, and which involves a simplified step in which heat treatment, which is performed for the purpose of having dimensional stability against heat, is not performed in the step after a nonwoven fiber web was formed. The method for producing a long fiber nonwoven fabric involves: a step (a) for obtaining a long fiber by melting a resin which has polyphenilene sulfide as the main component, and by pulling and stretching a thread, which was frozen and solidified after being ejected through a spinneret, at a spinning speed of 3,000m/min or more by means of an ejector, while heating said thread up to the ejector outlet; a step (b) for forming the long fiber into a nonwoven fiber web by collecting the long fiber on a moving net; and a step (c) for thermally adhering the resulting nonwoven fiber web.
