Abstract: The invention relates to a method and apparatus for drying wood by means of vapor. In the method according to the invention the vapor essentially is generated from the wood's own liquid by means of electric energy by conducting the electric energy by means of electrodes directly to the wood to be dried so that the vapor generated first in the center of the wood pushes out the liquids in the wood via the capillaries of the wood. The apparatus according to the invention includes a current source and electrodes connected thereto built to be brought into contact with the wood to be dried in order to conduct electricity to the wood.
