Beschreibung
Zusammenfassung:	A heat exchanger and a heat pump device that, with a small number of components, are capable of sending a refrigerant in a direction in which a plurality of heat transfer tubes are disposed side by side, the plurality of heat transfer tubes being connected to a header. An outdoor heat exchanger (11) includes a liquid header (30). The liquid header (30) includes a first liquid-side member (31) that includes a liquid-side flat-tube connection plate (31a) to which a plurality of flat tubes (28) are connected, a seventh liquid-side member (37) that includes a liquid-side external plate (37a) positioned on a side opposite to the flat tubes (28), and a fourth liquid-side member (34) that includes a fourth internal plate (34a) positioned therebetween. The fourth internal plate (34a) includes a first penetrationportion (34o) extending in a direction in which the plurality of flat tubes (28) are disposed side by side. The first penetrationportion (34o) has an introduction space (34x), a nozzle (34y), and an ascending space (34z) that are disposed side by side in order in the direction in which the plurality of flat tubes (28) are disposed side by side. The width of the nozzle (34y) is smaller than the width of the introduction space (34x) and is smaller than the width of the ascending space (34z).
