A cleaning tool, having a cleaning sheet and a holder for holding the cleaning sheet, wherein: the cleaning sheet extends 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 comprises 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 and 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, and 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, characterized in that the brush part has a first fiber bonded part which bonds the fibers of the fiber assembly in all of prescribed regions in a direction crossing the direction of fiber orientation and a second fiber bonded part which bonds the fibers of the fiber assembly in part of the prescribed regions in the direction crossing the direction of fiber orientation, the fibers have a connection end which is connected to the first fiber bonded part and an open end which is an end on the opposite side to the connection end, the first contact region is formed between the first fiber bonded part and the open end of the fibers, and the second contact region is formed between the first and second fiber bonded parts (140, 140A). the cleaning sheet extends 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 comprises 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 and 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, and 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, characterized in that the brush part has a first fiber bonded part which bonds the fibers of the fiber assembly in all of prescribed regions in a direction crossing the direction of fiber orientation and a second fiber bonded part which bonds the fibers of the fiber assembly in part of the prescribed regions in the direction crossing the direction of fiber orientation, the fibers have a connection end which is connected to the first fiber bonded part and an open end which is an end on the opposite side to the connection end, the first contact region is formed between the first fiber bonded part and the open end of the fibers, and the second contact region is formed between the first and second fiber bonded parts (140, 140A).
