Claim:
1. A side-flow type parallel-flow heat exchanger, comprising: a plurality of header pipes that are arranged parallel to each other at an interval; a plurality of flat tubes that are arranged between the plurality of header pipes and each have inside thereof refrigerant passages communicating with insides of the header pipes; and corrugated fins that are disposed between adjacent ones of the flat tubes, wherein the corrugated fins are longer than the flat tubes in a width direction, wherein the width direction is parallel to a wind direction and a longitudinal direction of contact portions between corrugation peaks of the corrugated fins and the flat tubes, the corrugated fins have protruding portions that do not make contact with the flat tubes thereby creating gaps, a linear water guide member is inserted into the gap between every adjacent protruding portion, a V-shaped notch is formed in each of the protruding portions where condensate water gathers, part of each of the corrugated fins is cut out only at one end thereof in the width direction so as to form the V-shaped notch, and the V-shaped notch is increasingly narrow from the one end in the width direction.
