An evaporator with a cool storage function includes a plurality of flat refrigerant flow tubes spaced apart from one another, and a plurality of flat cool storage material containers each of which contains a cool storage material and is disposed on one side of the corresponding refrigerant flow tube, and is brazed to the corresponding refrigerant flow tube. The cool storage material container includes a container body brazed to the corresponding refrigerant flow tube, and an internal-volume-increasing portion which extends downstream from the container body, which projects downstream from the refrigerant flow tube, and which is greater in dimension in a thickness direction than the container body. An inner fin extending from the container body to the internal-volume-increasing portion is disposed in the cool storage material container. This evaporator is suitable for a refrigeration cycle which constitutes a car air conditioner.
