To sufficiently heat gas for combustion, and to improve durability in a burner carrying out heating by transferring the heat of combustion gas to gas for combustion.
The burner includes first piping passing the gas for combustion through an interior, and second piping supplied with the gas for combustion blasted out of an opening of the first piping and formed with a combustion area burning the gas for combustion. The heating of the gas for combustion is carried out by transferring the heat of the combustion gas generated by the combustion of the gas for combustion to the gas for combustion via the first piping. The first piping has a heat transfer area 10 exposed to an environment having the same temperature or lower than an oxidation temperature of a forming material, having relatively high heat conductivity, and relatively low heat resistance, and a heat resistant area 20 exposed to an environment having the same temperature or higher than the oxidation temperature of the forming material of the heat transfer area 10 and having relatively high heat resistance in comparison with the heat transfer area 10.
