PURPOSE: A gas burner is provided to prevent the heat loss due to convection current by forming a heat insulating space. CONSTITUTION: A gas burner comprises a gas chamber(10), a casing(20), a fuel supply part(30), and a blower. The gas chamber has a chamber hollow in the inside, a first inlet(11) on one end, and an outlet(12) on the other end. The gas chamber is accepted in the casing hollow part of the casing. The casing has a combustion air channel and a second inlet(21). The combustion air channel is formed in the space of the casing hollow excepting the gas chamber. The combustion air flows in the second inlet. The fuel supply part is formed in the first inlet of the gas chamber of the casing. The fuel supply part supplies fuel to the chamber hollow of the gas chamber through the first inlet. The blower supplies combustion air to the first inlet through the combustion air channel.
