To provide high-quality woody veneer for shortening a manufacturing time, and reducing manufacturing cost.

The present invention is the woody veneer of slice-cutting raw wood (a log) or slice-cutting timber just after being heated by an electromagnetic wave such as a high frequency (3 MHz-300 MHz)or a microwave (300 MHz-300 GHz), and before and after electromagnetic wave heating and in slice-cutting time, a variation in the moisture content of the raw wood or the timber is not changed, and (the moisture content is restrained within ±5%), and the moisture content of the raw wood or the timber is also 10-30%, and the temperature (the internal temperature) of the raw wood or the timber by the electromagnetic wave heating is 40°C-90°C, and time up to the slice-cutting from the electromagnetic wave heating is within 2 hours, suitably, within 1 hour.
