The objective of the present invention is to provide a sterilizing sheet which is excellent in terms of saving space when a sterilizing operation is being performed, in terms of being capable of sterilizing objects of various sizes, and in terms of being capable of being stored when not in use, and which can moreover sterilize objects thoroughly. This sterilizing sheet 1 is provided with a flexible sheet body 2, a sheet accommodating body 3 and a handle 4. The sheet body 2 is formed from a dielectric 20 and a pair of electrodes 21 and 22 accommodated inside the dielectric 20. The sheet accommodating body 3 is a cylindrical body in which the sheet body 2 is accommodated in such a way as to be capable of being pulled out and rewound, and is provided with a case 30, a rotating body 31 and a rewinding mechanism 5. The rewinding mechanism 5 is a mechanism for automatically rewinding the sheet body 2, when pulled out from the sheet accommodating body 3, back into the sheet accommodating body 3. The handle 4 is attached to a distal end portion of the sheet body 2, and includes, inside the handle 4, a battery 41, a switch mechanism 42, a booster circuit 43 and a monitoring circuit 44.
