PURPOSE:To provide a heat disinfecting apparatus for a sand field, which can sterilize sand in a sand field in a simple operation at a low cost. CONSTITUTION:A mounted rod 2 is mounted on the end of a handle rod 1 so as to be almost orthogonal each other. The mounted rod 2 is vertically provided with a multiplicity of heating rods 4 which will be stuck into sand 3 in a sand field. The heating rods 4 comprise wire-like rods. This apparatus is constituted so that a person grasping the handle rod 1 can move it in the sand field while keeping the heating rods 4 to be stuck by pulling or pushing force. The heating rods 4 includes a heater 5 which heats by passing electricity through and raises the surface temperature of the heating rods 4 up to high temperature that can sterilize germs or microorganisms inhabiting in the sand field. |
