An elastically stretchable composite sheet includes an elastically stretchable first web and an inelastically stretchable second web of thermoplastic synthetic resin fiber which is intermittently bonded to the first web in a y-direction. Component fiber of the second web has its cress-section cut in a direction orthogonal to the y-direction defined by a width w and a height h dimensioned to be at a ratio h/w less than 0.5. The composite sheet having such a structure improve its flexibility.
