TELEPHONE BOX SNOW-MELTING DEVICE

PROBLEM TO BE SOLVED: To provide a telephone box snow-melting device capable of melting snow on the outside ground of the door of a telephone box, keeping the inside heating, simplifying construction of the device with a low construction cost as well as a low maintenance cost. SOLUTION: A plate heater 100 is laid on the ground located at just under the part projected from an opening and closing door 13 to the outside of a telephone box 10 when the opening and closing door 13 is opened. At the same time, a plate heater 100-2 is also laid on the ground located at just under the inside of the telephone box 10. The plate heaters 100 and 100-2 are plate bodies having specific thickness with a large number of approximately cone-shaped holes on the upper and lower surfaces, and the holes on both up and down surfaces are equipped with a honeycomb structural body having construction alternately arranged so as to have one side wall for common use, the honeycomb structural body is directly laminated to the upper surface or the lower surface or both surfaces of a plate-like heater or indirectly through another member, and they are formed together as a unit.
