Claims

[Scope of utility model registration request]

In a louvered fin in which a large number of louvers are formed on a thin metal plate, the front and rear edges of the louvers are formed into a wave shape by connecting a plurality of protrusions that become narrower toward the end. A fin with a louver, characterized in that each protrusion forming the waveform is bent relative to the main body of the louver.
