PROBLEM TO BE SOLVED: To provide a showcase reducing energy consumption by reducing the quantity of heat transferred from exhaust gas flowing through an exhaust ventilation passage, to cold air flowing through a cold air ventilation passage. SOLUTION: A back face cold air ventilation passage 22 and each exhaust ventilation passage 41a are arranged through a back face heat insulating plate 12 so that one end side in the width direction of the back face cold air ventilation passage 22 is located on the outside of one end in the width direction of the exhaust ventilation passage 41a with respect to one end side in the width direction of the exhaust ventilation passage 41a. Consequently, the quantity of heat transferred from exhaust gas flowing through the exhaust ventilation passage 41a to cold air flowing through the back face cold air ventilation passage 22 through the back face heat insulating plate 12, is reduced by making the adjoining area of the back face cold air ventilation passage 22 and exhaust ventilation passage 41a through the back face heat insulating plate 12 smaller than the back face side area of the back face cold air ventilation passage 22. Energy consumption is thereby reduced. COPYRIGHT: (C)2007,JPO&INPIT
