To provide a method for compounding, with high productivity, a composite including a poorly-adhesive material with keeping heat resistance and without performing a surface treatment.

In producing a composite including a nonwoven fabric having a layered structure of at least two layers including a poorly-adhesive material, a powdery or fibrous hot melt adhesive including 1 to 60 wt.% of a terpene resin-based or rosin resin-based tackifier on the basis of 100 wt.% of a polyethylene resin is used as an adhesive for compounding the composite.
