An object of the invention is to provide an effective cooling-energy storing performance and a stable cooling-energy radiating performance and to realize a high productivity. An evaporator has a plurality of refrigerant tubes arranged at almost equal intervals to form therebetween accommodating spaces. A plurality of cooling-storage containers are arranged in some of the accommodating spaces and fins are arranged in the remaining accommodating spaces. A cooling-storage unit is formed by one cooling-storage container and two refrigerant tubes arranged at both sides of the cooling-storage container. Each of the cooling-storage container has projections extending from one wall portion to the other wall portion to form heat exchange portions. The cooling-storage container is connected to the refrigerant tubes by soldering material.

A heat exchange tube having a flat shape includes a plurality of fluid paths having a circular cross section and extending in a longitudinal direction of the tube. Each fluid path is parallel to each other fluid path. The tube is dimensioned such that a distance between two adjacent fluid paths is defined as Wt, and a circumferential thickness between a surface of the tube and an outermost fluid path is defined as Ht. The distance Wt and the circumferential thickness Ht have a relationship as 0.42≦Ht/Wt≦0.98.
