抄録: The Kusunoki (Cinnamomum camphora) forest is in the Arboricultural Research Institute of the University of Tokyo Forest. Kusunoki was used as a feedstock for celluloid production, but nowadays, it has no industrial use. To examine the use Kusunoki as plywood, 21mm-thick plywood was manufactured from Kusunoki thinnings. The results obtained in a bending test were; MOR of 24.1 and 52.1 MPa and MOE of 4.8 and 7.3 GPa in the parallel and horizontal axes respectively. MOE values of Kusunoki veneer were estimated by parallel ply theory, and were almost equal to the literature values of Sugi, Hinoki, Karamatsu and Lauan veneer. Bond durability was sufficient to meet the requirements of the JAS standard for type II plywood. Values of 0.112 (W/mK) thermal conductivity, 1187 (J/kgK) specific heat and 1.58 × 10-7 (m2/s) thermal diffusivity were obtained. These values are equal to or greater than literature values of plywood for dwelling environment design. Thus, Kusunoki plywood shows suitable properties for use in nomal situations.
