To facilitate bending work parts at both ends at the time of applying embossing work over the whole surface of a metallic sheet used for the surface materials of construction materials such as wall panels.

The engraving of the shape imparting part (k) in both end parts in the axial direction of a pair of emboss-roll forming dies 1a, 1b is made shallower than the depth of the engraving in the shape imparting part (k) of the middle part and the depth (b) of the projecting and recessing parts in the bending parts Wb, Wb at both ends of the embossed metallic sheet W is formed shallower than the depth (a) of the projecting and recessing parts of the ornamental surface part Wa in the range of 30-70%, after that, workability at the time of bending in the bending part Wb is improved.
