The aim of this study was to evaluate mechanical properties of particleboard formed from rice husk particles by hot pressing with a polyvinyl alcohol (PVA) binder. The rice husk was ground to powder and sieved to a diameter range of 500-125 μm. A preform was prepared using mixed rice husk particles, PVA powder, and purified water. The rice husk particleboard was fabricated by the hot pressing with the preform. Some mechanical properties (flexural strength and flexural modulus) of resulting particleboard were evaluated by three-points bending test. The particle morphology and particle size was investigated by scanning electron microscopy and digital microscope. Results showed that mainly, the rice husk particleboards satisfied the reference flexural strength (the flexural strength is 13 MPa or more) and the reference flexural modulus (the flexural modulus is 2.5 GPa or more) of 13 type of base particleboard according to JIS A 5908
