PROBLEM TO BE SOLVED: To provide a timber laminated board which is surely hardly be bent even when a temperature or a humidity changes. SOLUTION: The timber laminated board 1 is formed by bonding a plurality of single plates 2 in a width direction, where both side edges are formed into projected and recessed shapes at a predetermined width in a direction perpendicular to the fiber direction of a timber, at predetermined amplitude and predetermined pitches with the fiber direction as an axis. Both side edges of the projected and recessed shapes are formed into wavy curves where amplitude S is set within a range of 0.5W≤S≤2.5W and a pitch P is set within a range of 5W≤P≤10W, wherein W indicates the width of the single plate 2, S indicates amplitude, and P indicates a pitch.
