PROBLEM TO BE SOLVED: To provide a refrigerating show case capable of uniformly heating the whole of glass without impairing visibility, removing dew condensation in a short time, and preventing dew condensation. SOLUTION: An air layer 24 is formed between glass 21 on the outdoor side and glass 22 on the indoor side, of which the glass window 2 of a refrigerating show case body consists, and a transparent conductive film 25 to prevent the impairment of visibility is mounted on a surface 21a on the indoor side of the glass 21 on the indoor side. By energizing the conductive film 25 by a power feeding means, the conductive film 25 is caused to generate heat through the generation of heat, the whole of the glass 21 on the outdoor side is uniformly heated, dew condensation of a surface 21b on the outdoor side of the glass 21 on the outdoor glass is warmed for evaporation, and dew condensation is removed in a short time. Further, since the whole of the glass 21 on the outdoor side is uniformly warmed by heating, the generation of fresh dew condensation is prevented.
