Provided is a palm material utilization method for efficiently separating palm material, such as oil palm material that has hitherto been left unutilized, into vascular bundles and parenchymatous cells and effectively utilizing the same. Also provided are a wood-based material in which separated vascular bundles are utilized and which is practically applicable for uses such as building material, and a method for manufacturing the wood-based material. Palm material is separated into vascular bundles and parenchymatous cells by means of pulverization, compression, blasting, high-pressure water jetting, or the like. A plurality of the separated vascular bundles are combined and bonded together using a resin material and are utilized as a wood-based material structural member. Meanwhile, the separated parenchymatous cells are utilized as a livestock feed or a raw material for bioethanol.
