- the cleaning liquid is supplied from the base end face 18 side
- the cleaning liquid supplied to the base end face 18 side can be selectively supplied from the exposed portion 17 to the substrate.
- the cleaning liquid is supplied into the cylindrical main body of the first roll cleaning member 52 and / or the second roll cleaning member 53, and the cleaning liquid is supplied to the substrate W from the tip of the nodule.
- a case where the substrate W is cleaned by a nodule can be mentioned (see FIG. 2).
- FIGS. 7A and 7B in the case where the base end face 18 is not covered with the skin layer 11, the cleaning liquid is introduced into the cleaning member 10 via the base end face 18.
- the supplied cleaning liquid can be efficiently provided from the front end surface 13 of the cleaning member 10 and the exposed portion 17 on the front end side to the substrate.
- the cleaning liquid is supplied to the sponge portion 12. This is advantageous in that it can be guided more easily.
- the distal end portion of the cleaning member 10 has a smaller sectional area (cross-sectional area) on the distal end side than a sectional area (cross-sectional area) on the proximal end side.
- the tip of the cleaning member 10 has a tapered shape and the vertical cross-sectional shape is trapezoidal, it is easily deformed. This is advantageous in that it can be gradually reduced toward the tip side.
- FIGS. 5 (e), (f), and (g) when the tip portion of the cleaning member 10 becomes smaller stepwise and the shape of the longitudinal section is a stepped shape is adopted. This is advantageous in that the shape of the tip of the deformable cleaning member 10 can be changed stepwise.
- the skin layer 11 when the aspect in which the cross-sectional area of the exposed portion 17 decreases continuously or intermittently from the boundary between the exposed portion 17 and the covering portion 16, the skin layer 11 is It is advantageous in that it can be easily manufactured by scraping at the tip side.
- FIGS. 5C and 5E when a mode in which the cross-sectional area of the exposed portion 17 is continuously or intermittently smaller on the tip side than the boundary between the exposed portion 17 and the covering portion 16 is adopted. Is advantageous in that the cross-sectional area of the exposed portion 17 that is easily deformed can be reliably reduced. As shown in FIGS.
- the cross-sectional area of the exposed portion 17 decreases continuously or intermittently from the base end side to the distal end side from the boundary between the exposed portion 17 and the covering portion 16. Adopting this aspect is advantageous in that it can be expected to prevent the exposed portion 17 from being excessively deformed.
