PROBLEM TO BE SOLVED: To provide a cleaning sheet, having high follow-up performance of long fibers especially for a rugged portion and excellent catching performance in the cleaning sheet in which a long fiber aggregate formed by aligning and assembling long fibers in one direction is joined to a base material sheet, and which is mounted on a head part in a cleaner including the head part and a shaft connected to the head part in use by utilizing the base material sheet. SOLUTION: In this cleaning sheet 1, the long fiber assembly 10 formed by aligning and assembling long fibers 11 in one direction is joined to one or both sides of the base material sheet 20 by one or two or more assemblies per side. The cleaning sheet 1 is mounted on the head part in the cleaner including the head part and the shaft connected to the head part and used by utilizing the base material sheet 20. The long fibers 11 in the long fiber assembly 10 are aligned in the cleaning direction D1 of the cleaner. The long fiber assembly 10 formed by assembling the long fibers 11 crimped with a crimp height of 0.1-5.0 mm is provided at least one per one side of the base material sheet 20.
