A heat exchanger includes a plurality of principal heat exchange sections and auxiliary heat exchange sections. Each of the auxiliary heat exchange sections is in series connection to a corresponding one of the principal heat exchange sections. Tube number ratios of the principal heat exchange sections are obtained by dividing the number of the flat tubes constituting each of the principal heat exchange sections to by the number of the flat tubes constituting a corresponding one of the auxiliary heat exchange sections. Of the principal heat exchange sections, the first principal heat exchange section, which is the lowermost one, has the smallest tube number ratio. Consequently, discharge of liquid refrigerant from a lower portion of the first principal heat exchange section is accelerated during defrosting, thereby shortening the time required for defrosting.
