Abstract:
A composite sheet used for a cleaning sheet (1) or the like is formed by joining a base layer (7) with grouped continuous fibers (8a) at a joint line (5). The joint line (5) consists of a first joint line (5A) formed on one side of an axis C-C which bisects the width of the grouped continuous fibers (8a) and a second joint line (5B) formed on the other side. The first and second joint lines (5A, 5B) cross the grouped continuous fibers (8a) obliquely so as to cross each other when extended toward the axis C-C.
