PROBLEM TO BE SOLVED: To provide a production method of laminated plywood, with which loss of a material to be used is reduced, cost is reduced, usage of a formaldehyde-based adhesive causing a sick house syndrome is suppressed, and which uses a component that oil palm originally has.SOLUTION: Laminated plywood is produced by arranging one or more oil palm thin boards W and any one or more of lauan thin board L, basswood thin board and conifer thin board facing the oil palm thin board W, and then they are compressed together, fixed and integrally joined together. The oil palm thin board W is formed, while rotating an oil palm trunk WD of a predetermined length in its circumferential direction, by skinning to a predetermined thickness on a rotary lathe, and it has thickness of 1 mm or more when the board is subjected to a compaction process. The lauan thin board L is formed, while rotating a lauan trunk LD, a basswood trunk, or a conifer trunk, of a predetermined length in its circumferential direction, and skinning to a predetermined thickness from an outer periphery on a rotary lathe. |
