Claim:
1. A heat exchanger comprising: a standing first header collecting pipe and a standing second header collecting pipe; a plurality of flat tubes which are arranged one above the other, which are each connected to the first header collecting pipe at one end and connected to the second header collecting pipe at the other end, and which are each formed with a passage of refrigerant; and a plurality of fins each configured to divide part of the heat exchanger between adjacent ones of the flat tubes into a plurality of air passages through each of which air flows, wherein the flat tubes are divided for an internal space of the first header collecting pipe is divided into an internal space of the second header collecting pipe is divided into each communication space of the second header collecting pipe corresponding to the upper heat exchange region communicates with an associated one of the plurality of communication spaces of the second header collecting pipe corresponding to the lower heat exchange region, wherein the number of flat tubes connected to a communication space of the second header collecting pipe corresponding to the upper heat exchange region is larger than the number of flat tubes connected with the associated one of the plurality of communication spaces of the second header collecting pipe corresponding to the lower heat exchange region with which it communicates.
