PROBLEM TO BE SOLVED: To provide a reinforced drawn nonwoven fabric improved in tear strength, while making effective use of characteristics of a drawn unidirectionally-oriented nonwoven fabric, and capable of being suitably used as a sheet or a base material in fields of a wide variety. SOLUTION: This reinforced drawn nonwoven fabric 1 has a base material layer 2 and a netlike sheet 3 which is compressedly adhered to one of surfaces of the base material 2 so as to be laminated. The base material layer 2 is given by orienting fibers made of a thermoplastic resin in an approximately one direction and drawing the fibers in the direction of orienting the fibers so as to form two pieces of the drawn unidirectionally-oriented nonwoven fabrics 2a, 2b, and then arranging and laminating the formed two pieces of the fabrics in such a manner that directions of the oriented fibers of the two pieces are rectangularly crossed to each other. The netlike sheet 3 is composed of two or more of longitudinal strands which are oriented in the longitudinal direction by maintaining a distance from each other and two or more transverse strands which are oriented in the transverse direction by maintaining another distance from each other, wherein the longitudinal strands and the transverse strands are bonded to each other at their intersecting points.
