The shape of wood flour that is subjected to the chemical treatment process is processed such that it has a major radius of 10 to 40 μm and a minor radius of 5 to 20 μm at the point where number accumulation in a particle size and shape distribution measurement is 50%. After that, degreasing treatment, delignifying treatment, and hemicellulose removing treatment are carried out in this order in the chemical treatment process. The delignifying treatment is carried out in a temperature range of 70 to 99°C and in a pH range of more than 3 and 7 or less.
