A cleaning tool has a tray 10 and a cover member 20. The tray has a space for individually accommodating a to-be-cleaned object D. The cover member has a frame 21, and thread-like members 22 and 23. The thread-like members 22 are tensioned to the frame along a first direction so as to form a first plane section that defines the top portion of the space. The thread-like members 23 are tensioned to the frame along a second direction so as to form a second plane section above the first plane section. When the thread-like members 22 are about to vibrate during the cleaning, the thread-like members 23 restrict this vibration. Further, each thread-like member can relatively freely move in each plane section.
