The present invention is to provide a three-dimensional board structure and method thereof by sequentially coating an adhesive on a plurality of veneers containing plant fibers, sequentially bonding the veneers together to form a multilayer board, penetrating and pressing the multilayer board by using a plurality of spikes arranged on a tool for deforming and breaking the plant fibers around peripheries of penetrated portions of the veneers, and removing the spikes from the multilayer board, such that the plant fibers around the peripheries of the penetrated portions of any two adjacent veneers are entangled with each other to form three-dimensional connecting portions in the multilayer board. Since the adhesive will permeate into the three-dimensional connecting portions due to penetration of the spikes and pressure of the tool, the three-dimensional connecting portions between the adjacent veneers and the adhesive permeated therein make the multilayer board having a three-dimensional bonding strength accordingly.
