열 가소성 엘라스토머 섬유로 이루어지는 극세 섬유층과 비극세 섬유층의 일체성이 우수한 섬유 적층체를 제공한다. 상기 섬유 적층체는, 열 가소성 엘라스토머 섬유로 이루어지는 평균 섬유 직경 10 ㎛ 미만의 극세 섬유층과, 상기 극세 섬유층에 인접하여 평균 섬유 직경 10 ∼ 30 ㎛ 의 섬유로 이루어지는 비극세 섬유층을 갖고, 상기 극세 섬유층과 비극세 섬유층의 층간 박리 강력이 0.40 N/5 ㎝ 이상이고, 섬유 적층체 표면의 요철차가, 섬유 적층체의 두께에 대하여 40 ％ 이하이다. Provided is a fiber layered body with excellent integrated structure including: an extra-fine fiber layer containing thermoplastic elastomeric fibers; and a non-extra-fine fiber layer. The fiber layered body includes: an extra-fine fiber layer which comprises thermoplastic elastomeric fibers and has an average fiber diameter of less than 10 µm; and a non-extra-fine fiber layer containing fibers having an average fiber diameter of 10 to 30 µm and adjacent to the extra-fine fiber layer. The fiber layered body has a peeling strength between the extra-fine fiber layer and the non-extra-fme fiber layer of 0.40 N/5cm or higher, and has an surface unevenness relative to a thickness of the fiber layered body of 40% or less.
