Abstract A process for making an elastically stretchable composite sheet having a relatively low basis weight. An elastically stretchable second web is placed upon a first web 41 comprising stretchable first continuous fibers 35 and these first and second webs 41, 42 are intermittently bonded together at bond regions 4A to obtained a first composite web 43 which is, in turn, stretched under a plastic deformation of the first continuous fibers 35 and then elastically contracted. Thereafter, the first and second webs are supplementarily bonded together at second bond regions 4B to obtain a second composite web 44 as the elastically stretchable composite sheet.
