Abstract
This invention aims to provide a composite sheet having a layer of inelastically stretchable continuous fibers improved so that a possible unevenness in fiber diameter may be minimized. A composite sheet comprises an elastically stretchable layer and an inelastically stretchable layer formed with inelastically stretchable continuous fibers bonded to at least one surface of the elastically stretchable layer intermittently in one direction. The continuous fibers are oriented substantially in one direction thereof so that the composite sheet may present a ratio S/Sof 3.0 or higher where Srepresents a tensile strength in this one direction and Srepresents a tensile strength in the direction orthogonal to this one direction.
