Second heat exchange tubes forming a second heat exchange path provided in a super-cooling part are connected to the second header tank. The first header tank has one communication section which communicates with the second header tank through a communication part and to which all the heat exchange tubes forming the first heat exchange path are connected. The communication part is provided at a height below the uppermost heat exchange tube among all the heat exchange tubes connected to the communication section.
