PROBLEM TO BE SOLVED: To provide a show case capable of heating merchandises inside an exhibition chamber to be at appropriate temperature by avoiding the lowering of in-exhibition-chamber air temperature due to outdoor temperature, etc.SOLUTION: A show case 1 includes: lamp heaters 16-18 arranged above placement surfaces for exhibiting the merchandises of the show case 1; a cord heater 12 arranged in heat exchange relation with the placement surface; an in-exhibition-chamber air temperature sensor 21 for detecting air temperature inside the exhibition chamber; a placement surface temperature sensor 13 for detecting the temperature of the placement surface; and a control device for controlling the electrification of the cord heater. The control device controls the electrification of the cord heater on the basis of the temperature of the placement surface to be detected by the placement surface temperature sensor and the preset temperature range of the placement surface and also on the basis of the in-exhibition-chamber air temperature to be detected by the in-exhibition-chamber air temperature sensor and the preset temperature range of the air temperature. |
