To provide a stove hardly exhausting black smoke in regard to a stove of a chimney connection type inputted with fuel such as firewood and burning it.

A filter composed of thin film metal having temperature rise followability for providing a high temperature, and sufficient enough for trapping and re-burning unburned gas and particulate matter even when the stove has just been lighted, is attached to a lower part side space part 2 side of a communication part 3 provided in a partition object 4. By this, the particulate matter such as black smoke generated in a combustion space part 2A is trapped and re-burned. Exhaust of the particulate matter from a chimney is reduced by passing air to be supplied to the combustion space part 2A through an ash holding part 14 and a lower part space part 2, raising a temperature of the supply air, guiding it to the combustion space part 2A, gasifying solid fuel such as firewood, and carrying out high temperature combustion.
