1. A heat exchanger comprising:

  • a heat exchanging portion configured by stacking a plurality of refrigerant tubes through which a refrigerant in a vapor-compression refrigeration cycle flows, and a plurality of heat medium tubes through which a heat medium flows to exchange heat with the refrigerant; and

    a tank portion provided with at least one of a refrigerant tank space adapted to collect or distribute the refrigerant with respect to the refrigerant tubes, and a heat medium tank space adapted to collect or distribute the heat medium with respect to the heat medium tubes, whereinthe heat exchanging portion and the tank portion are formed by bonding plate members,the heat exchanging portion includes a first heat exchanging portion in which heat is exchanged between the heat medium and the refrigerant on a high-pressure side of the vapor-compression refrigeration cycle, and a second heat exchanging portion in which heat is exchanged between the heat medium and the refrigerant on a low-pressure side of the vapor-compression refrigeration cycle,the tank portion is provided with a refrigerant inlet that allows the refrigerant to flow into the refrigerant tank space, a refrigerant outlet that allows the refrigerant to flow from the refrigerant tank space, a heat medium inlet that allows the heat medium to flow into the heat medium tank space, and a heat medium outlet that allows the heat medium to flow from the heat medium tank space, andat least one of the refrigerant inlet, the refrigerant outlet, the heat medium inlet, and the heat medium outlet is disposed between both ends of the tank portion in a tube stacking direction of the refrigerant tubes and the heat medium tubes.
