PROBLEM TO BE SOLVED: To provide a method for inexpensively manufacturing a woody composite base material excellent in surface smoothness and surface hardness as a base material, hard to cause warpage (especially width warpage) and gap (especially a gap in a width direction) and suitable for double-sided decorative bonding. SOLUTION: The manufacturing method of the composite base material obtained by stacking and bonding medium specific gravity fiberboard to both front and back of a woody plate has a process for dividing the medium specific gravity fiberboard in its thickness direction to obtain sheets and a process for stacking and bonding the sheets, a plurality of woody veneers and in this order by one clamping so that the hard layer sides of the sheets are directed outside, an odd number of the woody veneers are used so that the fiber directions of them almost cross at a right angle each other, the fiber directions of the woody veneer of the second layers from the surface and back sides of the composite base material are allowed to be orthogonal to the longitudinal direction of the composite base material almost.
