A finned tube heat exchanger includes a plurality of tube arrays, each of which includes a plurality of heat transfer tubes that each extend parallel to one another and are disposed at a predetermined pitch in a first direction that intersects a flow direction of heat exchanging air, in a second direction that intersects the first direction, any closest two of the plurality of tube arrays having a predetermined distance therebetween. One closest two tube arrays includes first and second tube arrays that respectively include a plurality of first heat transfer tubes and a plurality of second heat transfer tubes. When seen from the flow direction, each first heat transfer tube is disposed closer to one of an adjacent two second heat transfer tubes that is closest to said each first heat transfer tube, than to the other one of the adjacent two second heat transfer tubes.
