ABSTRACT:
In a corrugated fin which is formed and bent into a wave-form, a plurality of both-side-cut-louvers8, which are laminated on each other and formed into a group, and one-side-cut-louvers7, which are arranged at end portions of the group of both-side-cut-louvers8, are formed being raised, and a cross-section in the louver laminating direction of at least one of the one-side-cut-louvers7is formed into a substantial V-shape. An inclined face70of the one-side-cut-louver7adjoining the both-side-cut-louver8is made to cross a centerline in the fin thickness direction and a length of the inclined face70is made to be the same as that of the inclined face of the adjoining both-side-cut-louver8.
