採用されている。2. Description of the Related Art Conventional plywood is generally formed by joining veneers having a vertical or horizontal grain to three layers so that the grain is in a vertical, horizontal and vertical order, or a horizontal, vertical and horizontal order. Various materials, such as hardwood materials or softwood materials, and combinations thereof, are employed depending on the application.

限られ、また耐用期間も十分とはいえなかった。[0003] However, such plywood having a layered structure in which the grain is perpendicular to the grain has excellent strength (compression, tension, etc.) in the direction along the grain of each veneer, but is oblique to the grain (eg, 45 mm). The strength of (degree) is generally insufficient, and warpage or dimensional deviation is apt to occur. Therefore, the field of use is limited, and the service life is not sufficient.

い欠点がある。As for plywood materials, hardwoods are generally hard and have good strength. However, as in the case of rawan wood, for example, depletion of resources in Southeast Asia, which is the region where the wood is produced, rise in price, or environmental protection In view of the above, there are some woods that are gradually becoming difficult to obtain, so that the material for plywood is being converted from hardwood to conifer. However, while softwoods are relatively rich in resources and are readily available, and the materials are relatively soft and easy to process, the plywood has the drawbacks that it is somewhat low in strength and that warpage and dimensional irregularities are likely to occur.
【０００５】そこで、針葉樹を用いても、強度が全方位
