And a second sticking step of sticking the decorative sheet 2A to at least the surface side portions 15 and 18 on both end faces in one direction (longitudinal direction). Therefore, the decorative sheet 2 </ b> A can be attached in a series to the surface 11 of the base material 10 </ b> B constituting the plate-shaped building material 1 and at least the surface side portions 12, 13, 15, 18 of the end faces on the four circumference sides. As a result, when a plurality of plate-like building materials 1 are arranged side by side in the vertical and horizontal directions, even when gaps are generated in these joint parts, at least the surface side parts 12, 13, 15, 18 of the four-circumferential side end faces. Since the decorative sheet 2A is adhered, the base material 10B can be made inconspicuous. Moreover, the moisture absorption etc. of the base material 10B can be suppressed.

  Moreover, in the said 1st sticking process, the ditch | groove part formed so that the surface side site | parts 15 and 18 of the both-sides end surface of one direction might be comprised so that it might extend in another direction over the whole other direction orthogonal to one direction. The decorative sheet 2 is adhered to the surface 11 of the base material 10A so as to cover 14 and 17. Further, in the end face processing step (longitudinal end face processing step), so as to leave the portions 3 and 6 covering the concave groove portions 14 and 17 of the decorative sheet 2 and to form the back side portions of the both end surfaces in one direction. It is configured to perform processing. That is, it is set as the structure which provided the concave-groove part 14 and 17 for ensuring the decorative sheet 2A stuck to at least the surface side site | parts 15 and 18 of the both-sides end surface of one direction in base material 10A itself.
