PROBLEM TO BE SOLVED: To provide laminated lumber 1 which is low in dimensional change rate and volume/weight increase rates, high in flexural strength, block shearing strength, etc., and excellent in dimensional stability and various physical properties. SOLUTION: In the laminated lumber 1, a number of small square wood pieces 11 or small rectangular wood pieces 12 of a prescribed thickness are laminated/bonded. The wood pieces 11 and 12 are arranged horizontally. Wood fibers are arranged in multiple directions. In the vertical arrangement of the fibers, they are arranged alternately. The wood pieces 11 and 12 are laminated/bonded together through the application of an adhesive.
