Provided is a composite stretchable material that is thinner and has more uniformly sized creases. The composite stretchable material is stretchable in a first direction (D1) and is provided with a first non-woven fabric sheet portion (2A) and second non-woven fabric sheet portion (2B) placed atop each other, and a plurality of elastic members (3) arranged between the first non-woven fabric sheet portion (2A) and the second non-woven fabric sheet portion (2B). The elastic members (3) extend in the first direction (D1) and are spaced apart from each other in a second direction (D2) orthogonal to the first direction (D1), and the first non-woven fabric sheet portion (2A) and the second non-woven fabric sheet portion (2B) are bonded to each other by an adhesive that has been applied to the elastic members (3).
