PROBLEM TO BE SOLVED: To provide a method and a device for sterilizing soil through uniform heating over a wide range stably for a long period of time with reduced influence attributable to external conditions. SOLUTION: The method for sterilizing soil comprises covering soil surface with sheets including a flexible planar exothermic element capable of temperature control and heating the soil under the control through the exothermic element. The device is basically constituted of the planar exothermic element integrated by sandwiching an exothermic element between flexible resin sheets and a temperature control unit functioning to control the temperature of the planar exothermic element, and the soil surface side of the planar exothermic element and the other side are provided with a flexible moistureproof sheet and a flexible thermal insulation material, respectively.
