PROBLEM TO BE SOLVED: To provide a decorative base plate conifer composite plywood in which a surface or both surfaces of a conifer plywood are adhered with a wet type hard fiberboard (hard board), and a defect does not appear on a decorated surface, since a defect such as a knot appears on a decorated surface of a conifer plywood as a defect, and it is difficult to make a decorative conifer plywood.SOLUTION: A surface or both surfaces of a conifer plywood 2 are adhered with a wet type rear face embossment layer 4 formed at a rear face of a wet type hard fiberboard (hard board), and a knot 3 or the like that is a defect of a conifer plywood is embedded with a rear face embossment layer in which a specific gravity is low. Moreover, gas change such as a recess is performed by internal absorption by a layer of a rear face of a wet type hard fiberboard (hard board) in which a specific gravity is low. |
