Abstract
Nonwoven fabric has a plurality of groove portions continuously formed along a predetermined direction, and a plurality of raised ridge portions formed continuously along the groove portions, each adjacent to the groove portions. The basis weight is the least, and the content percentage of laterally-oriented fibers is high, and the content percentage of longitudinally-oriented fibers is low at the groove portions of the nonwoven fabric. Sides at the raised ridge portions are formed so that their basis weight is the greatest, and the content percentage of the fiber oriented toward a longitudinal direction is high.
