HEAT EXCHANGER AND AIR-CONDITIONING DEVICE

A support plate (48) is provided at an end of a fin group (47). End portions of a plurality of heat transfer tubes (50) form protrusions (51) protruding from the support plate (48). The protrusions (51) include a first protrusion (51a) and a second protrusion (51b). The first protrusion (51a) is connected to the protrusion (51) positioned adjacent to the first protrusion (51a). The second protrusion (5 1b) is connected to a flow path pipe different from the protrusion (51) positioned adjacent to the second protrusion (51b). A distance from the tip end of the second protrusion (51b) to the support plate (48) is shorter than a distance from the tip end of the first protrusion (51a) to the support plate (48).
