PROBLEM TO BE SOLVED: To realize a cleaning sheet of good efficiency which consists of a sheet of nonwoven fabric and prevents dust from slipping on a cleaning surface and to provide its manufacturing method. SOLUTION: Pleat parts 61 having narrow part 62 for catching dust are formed continuously at optional intervals in one direction of the one sheet of nonwoven fabric. Joint parts 63 are formed continuously at the nonwoven fabric 1 at optional intervals in a direction orthogonal to the one direction. The nonwoven fabric 1 is provided with a protrusion part 32 having opening parts 31 at mutually different positions between both of its surfaces. |
