A hydrogen gas burner structure comprising: a first cylinder tube of which a tip is open, an inside of the first cylinder tube being configured such that hydrogen gas (G1) flows toward the tip of the first cylinder tube ; a second cylinder tube disposed outside the first cylinder tube concentrically with the first cylinder tube , a space between the first cylinder tube and the second cylinder tube being configured such that a first combustion-supporting gas (G2) containing oxygen gas, for primary combustion of the hydrogen gas (G1), flows toward a tip of the second cylinder tube ; a third cylinder tube disposed outside the second cylinder tube concentrically with the first cylinder tube and the second cylinder tube , a space between the second cylinder tube and the third cylinder tube being configured such that a second combustion-supporting gas (G3) containing oxygen gas, for secondary combustion of the hydrogen gas (G1), flows toward a tip of the third cylinder tube ; and an ignition device disposed inside the second cylinder tube , the ignition device being configured to ignite mixed gas obtained by mixing the hydrogen gas (G1) and the first combustion-supporting gas (G2) with each other, wherein the tip of the first cylinder tube is located upstream of the tips of the second and third cylinder tubes in a gas flow direction in which the hydrogen gas (G1) and the first combustion-supporting gas (G2) and the second combustion-supporting gas (G3) flow; characterised in that : the tip of the third cylinder tube is located upstream of the tip of the second cylinder tube in the gas flow direction. a first cylinder tube of which a tip is open, an inside of the first cylinder tube being configured such that hydrogen gas (G1) flows toward the tip of the first cylinder tube ; a second cylinder tube disposed outside the first cylinder tube concentrically with the first cylinder tube , a space between the first cylinder tube and the second cylinder tube being configured such that a first combustion-supporting gas (G2) containing oxygen gas, for primary combustion of the hydrogen gas (G1), flows toward a tip of the second cylinder tube ; a third cylinder tube disposed outside the second cylinder tube concentrically with the first cylinder tube and the second cylinder tube , a space between the second cylinder tube and the third cylinder tube being configured such that a second combustion-supporting gas (G3) containing oxygen gas, for secondary combustion of the hydrogen gas (G1), flows toward a tip of the third cylinder tube ; and an ignition device disposed inside the second cylinder tube , the ignition device being configured to ignite mixed gas obtained by mixing the hydrogen gas (G1) and the first combustion-supporting gas (G2) with each other, wherein the tip of the first cylinder tube is located upstream of the tips of the second and third cylinder tubes in a gas flow direction in which the hydrogen gas (G1) and the first combustion-supporting gas (G2) and the second combustion-supporting gas (G3) flow; characterised in that : the tip of the third cylinder tube is located upstream of the tip of the second cylinder tube in the gas flow direction. <EOS>
