To provide a light and rigid door pocket panel by forming a core board by sticking cardboard to both surfaces of a paper core, and sticking a surface material only to one surface of the core board.

The door pocket panel 11 is composed of the core board 12 and the surface material 13, and the surface material 13 is stuck to one surface of the core board 12. That is, the door pocket panel is constituted without sticking a conventional reverse material to an opposite surface. The core board 12 is constituted by sticking cardboard 15, 15 to both surfaces of a paper core 14. The surface material 13 stuck to the core board 12 is stuck over the whole surface to cardboard 15 of a surface, and is stuck not in line adhesion such as being adhered to a conventional paper core, bus is stuck by forming a uniform flat plane by completely fixing the surface material 13. Thus, the surface material becomes the door pocket panel having a flat surface without waving a recess/projection shape even if it is relatively thin. Due to the whole surface adhesion, even if external force acts, recessing deformation can be prevented.
