Abstract (en)

In the louver fin (11), a plurality of louvers (19, 21) cut and bent out of the flat portions (17) along the longitudinal direction Y of the strip thin sheet (13) are arranged parallel to each other along the width direction X of the strip thin sheet (13). In the louver fin (11) the louvers (18, 19) are cut and bent at an approximately same angle with respect to the longitudinal direction Y of the strip thin sheet (13).
