Abstract
A woody material, where a ratio (HB/HA) between a height (HA) of an absorption peak derived by C—H stretching vibration detected at a wavenumber from 2850 cm-1 to 2950 cm-1 and a height (HB) of an absorption peak derived by skeletal vibration of an aromatic ring detected at a wavenumber from 1480 cm-1 to 1540 cm-1 is 1.10 or less in an ATR spectrum of an inside or a surface of the woody material by an infrared spectroscopic analysis method.
