To provide a pellet stove with a novel composition capable of forcibly sending hot air into a room.

A combustion box 30 is composed of a thin plate, an air chamber 38 for combustion is formed in an interior, and a multiplicity of small holes 40 is provided for communicating the air chamber 38 for combustion with a combustion space 36. Side faces and a top face of a combustion chamber 34 are composed of thin plates with a double structure, an air chamber 70 for hot air is formed around the combustion chamber 34, and hot air blowout openings 72, 74, and 76 are formed for communicating the air chamber 70 for hot air with air in the room. Respective air inlet parts 38A and 70A of the air chamber 38 for combustion and the air chamber 70 for hot air are coupled, and an air blowing fan 44 is arranged in the coupling part. One part of air blown from the air blowing fan 44 is sent to the air chamber 38 for combustion. The rest is sent to the air chamber 70 for hot air, heated by high temperature in the combustion chamber 34, and sent into the room through the hot air blowout openings 72, 74, and 76.
