摘要：
This composite stretch material (3) which is composed of a first nonwoven fabric sheet part and a second nonwoven fabric sheet part (1U, 1L) and elastic members (2) disposed therebetween. In each nonwoven fabric sheet part, concave parts (51) and convex parts (53) are formed in the thickness direction. The concave and convex parts formed alternately repeatedly in a first direction define convex-concave rows (41). The convex-concave rows are separated from each other by non-shaped regions (43) which contain neither concave parts nor convex parts and which extend along the first direction. The non-shaped regions are joined to each other with the elastic member therebetween. The convex parts of the first nonwoven fabric sheet part enter respectively into the concave parts of the second nonwoven fabric sheet part, while the convex parts of the second nonwoven fabric sheet enter respectively into the concave parts of the first nonwoven fabric sheet part.
