PROBLEM TO BE SOLVED: To prevent the dropping-off of a cooling pipe from a cooling plate in a refrigerator adapted to cool a cooling chamber by the flat cooling plate. SOLUTION: A cooling chamber evaporator 11 having the cooling pipe 13 arranged in thermal contact with the flat cooling plate 12 and a decorative plate 14 are longitudinally inclined in the same direction between an inner box 1 and the decorative plate 14, and the cooling pipe having a vault section is arranged on the lower surface of the longitudinal inclination with an arrangement pattern of winding and curving in a horizontal U-shape, and both straight pipes extended from the round part thereof are extended and fixed in a sector shape to circulate cold air from above to down. According to this, dew condensate on the cooling plate or cooling pipe surface, which generates in heat exchange, can be surely carried to a lower drain port. Thus, not only the refrigerator can be regularly used at the highest heat exchange efficiency, but also the dropping-off of the cooling pipe from the cooling plate can be prevented.
