PROBLEM TO BE SOLVED: To provide a method for manufacturing a particle board capable of having a sufficient strength and dimensional stability, and the particle board. SOLUTION: Wood chips are impregnated with a binder to improve a strength of the chip themselves, and rigidly bonded among the chips to each other to improve a strength of the particle board. Since a water absorption ratio of the chips is suppressed by impregnating the chips with the binder, its swelling rate is suppressed to improve dimensional stability. Further, as the binder, a phenol resin is sued, and the board having a higher strength and excellent dimensional stability is manufactured. The chips are hot press molded by a high pressure hot press, the board having a high density surface part and a low intermediate part is manufactured. The board having a predetermined strength and dimensional stability can be obtained by this method.
