A lower face of a base body (15) includes a wave-like corrugated surface portion (19) of which cross-section in a direction perpendicular to a predetermined direction along which cleaning is performed with a cleaning device body (11) in a planar view is wave-shaped as having a ridge portion (17) and a valley portion (18) arranged alternately and continuously. The valley portion (18) of the wave-like corrugated surface portion (19) includes an oblique valley portion (18a) of which end part is opened to a side portion of the base body (15) facing to the predetermined direction as being extended obliquely against the predetermined direction to obliquely guide objects such as dust to be stuck to a cleaning sheet (13) in accordance with wiping of the surface to be cleaned. |
