Abstract: A filing tool (1) for filing one or more sheets 6 provided with a magnetically attractable area (7) on a side end or periphery of the sheet is composed of a two-folded cover member (2) having a back (2a), an electromagnet (3) situated along the back (2a), an and an ON-OFF switch (5) for changing "ON" to "OFF" or "OFF" to "ON" for flowing a current to the electromagnet (3). Thereby, the sheet can be readily attracted by the cover member and can be readily detached therefrom by operating the ON-OFF switch. Further, even an intermediate sheet can be easily picked up.
