Abstract
A unidirectionally stretchable substrate which has good shape retaining characteristics and whose weight can be easily reduced is provided. Unidirectionally 1 stretchable substrate has meshed material 2 that has a plurality of elastomeric linear members 3 arranged orthogonal to each other, the linear members having stretchability and thermoplasticity; and non-woven fabric 4 that is formed of a plurality of filaments 5, the filaments being made of a thermoplastic resin. Filaments 5 of non-woven fabric 4 have been drafted in one direction and are linearly arranged only in that direction. Non-woven fabric 4 is bonded to meshed material 2 such that direction y in which filaments 5 of the non-woven fabric 4 are arranged is parallel with one of directions y in which linear members 3 of meshed material 2 extend.
