In order to solve the above problem, according to a preferred aspect of the present invention, a cleaning tool having a cleaning sheet and a holder for holding the cleaning sheet is provided. The cleaning sheet is configured to extend in a longitudinal direction which is defined by a direction of insertion of the holder into the cleaning sheet, in a transverse direction which is defined by a direction crossing the longitudinal direction, and in a thickness direction which is defined by a direction crossing the longitudinal direction and the transverse direction. The holder has a holding part for holding the cleaning sheet, and a grip part which is connected to the holding part and designed to be held by a user. The cleaning sheet has ends in the longitudinal direction, ends in the transverse direction, a brush part capable of cleaning an object to be cleaned, a base connected with the brush part, and an insertion part which is formed on the base and into which the holding part is inserted. The brush part has a fiber assembly of fibers having a prescribed direction of fiber orientation and a contact region which comes in contact with the object to be cleaned. The contact region includes a first contact region and a second contact region. The second contact region has a low region which is configured to be lower than the first contact region in the thickness direction. The low region forms a guide region which is capable of guiding dust on the object to be cleaned to the adjacent first contact region.
