To provide a method for producing a laminate composed of a plurality of spun-bonded non-woven fabric layers, in which the laminate is excellent in great softness and voluminosity and is excellent in adequate stiffness and strength.SOLUTION: The method for producing a laminate having at least two spun-bonded nonwoven fabric layers comprises: compressing or pre-consolidating a first spun-bonded nonwoven fabric layer 2 produced by deposited non-crimping continuous filaments and/or slightly crimping continuous filaments with at least one heating roller and/or calender roller 4; depositing a second spun-bonded nonwoven fabric layer 3 composed of crimping continuous filaments on the first spun-bonded nonwoven fabric layer 2; and fixing an assembly composed of both spun-bonded nonwoven fabric layers thereby having the total thickness of the laminate 1 of 0.15 to 3 mm.SELECTED DRAWING: Figure 1 【課題】複数のスパンボンド不織布層から成る積層体の製造方法であって、高い柔軟性と嵩高性が優れているとともに、十分な剛性と強度が優れている積層体の製造方法の提供。【解決手段】非捲縮性および／または微捲縮性の連続フィラメントが堆積されてなる第一のスパンボンド不織布層２を、少なくとも１つの熱ロールおよび／またはカレンダーロール４によって圧縮または予備固定し、それに引き続き、第一のスパンボンド不織布層２上に、捲縮性の連続フィラメントからなる第二のスパンボンド不織布層３堆積し、その後に、両者のスパンボンド不織布層から成る集合体を固定することで、積層体１の全厚さを０．１５〜３ｍｍとする、少なくとも２層のスパンボンド不織布層を有する積層体の製造方法。【選択図】図１
