To provide a wood stove usable even in a urban area, retaining high temperature by accumulating unburnt gas in a secondary combustion chamber without using a catalyst, efficiently burning the unburnt gas by supplying a sufficient amount of air from an exterior, providing a highly efficient heating effect, and at the same time, reducing black smoke of exhaust air.

A horizontal air supply pipe 17 taking in air flowing in from an air mount regulating valve 14 of a wood input port 15 is provided in a main combustion chamber 11, the horizontal air supply pipe 17 is provided with a plurality of air holes 18 on a side face in an opposite direction of the wood input port 15, and a secondary combustion tube 20 is provided on an upper side of the combustion chamber 11 in a side opposite to the wood input port 15. The secondary combustion tube 20 has a plurality of air amount adjusting pipes capable of adjusting and supplying an outside air amount from a side direction, a connection plate 21 is provided in its lower part, and a convection suppressing plate 25 is provided in its upper part. A secondary combustion chamber 26 is composed between the two plates, and an eddy current forming blade 27 is composed on a wall of an exhaust chamber 25 being a space above the convection suppressing plate 25.
