In the deformation step, the guide hole is held. Furthermore, in the deformation step, the side-view shape of the fin material is deformed by bending the boundary portion between the first region and a second region so that the second region becomes either a peak part or a valley part. The second region is a region of the fin material which is brought into contact with the flat tube and a region adjacent to the first region in the length direction of the fin material.
