To provide a method for producing a pinhole-free dense nonwoven fabric having air-permeability and including localized fibrillated fiber.

The method for producing the fibrillated fiber-localized nonwoven fabric in which the fibrillated fiber is localized and the content of the fiber in the inside is higher than that at the surface is provided. The method for producing the fibrillated fiber-localized nonwoven fabric comprises sending out the first raw material slurry in which the content of the fibrillated fiber is lower than that in the second raw material slurry on a screen net of a paper machine, squeezing the water of the slurry to form a wet web, sending out the second raw material slurry in which the content of the fibrillated fiber is higher than those of the first raw material slurry and the third raw material slurry on the wet web, squeezing the water to form a wet web, sending out the third raw material slurry in which the content of the fibrillated fiber is lower than that of the second raw material slurry thereon, and making the paper thereof by a wet papermaking process.
