To provide a wiper facilitating a wiping work.

A sheet-shaped material 20 having a wiping function is stored in a case member 30 with a cushion material 10. Since the case member 30 functions as a grasping part, a user has to only grasp the case member 30 and move forward/backward/rightward/leftward the sheet-shaped material 20 abutting on a display or a mirror to be wiped. Since it is not needed to press the sheet-shaped material directly with fingers unlike in conventional devices, resistance is small, which allows the wiper to be moved forward/backward/rightward/leftward with small force, thereby improving workability of wiping. Consequently, the wiper is appropriate to wipe a ≥15 in display larger than the display screen of a cellular phone, a mobile game machine, etc., or a mirror etc. as large as the display.
