PROBLEM TO BE SOLVED: To stabilize and simplify a structure of an oxidizing air feed pipe to be disposed in an auto-oxidation internal-heating reformer. SOLUTION: The auto-oxidation internal-heating reformer is equipped with an outer cylinder 2, an inner cylinder 3 disposed therein and the oxidizing air feed pipe 14 disposed at the center of the inner cylinder 3. A preliminary reforming chamber is formed between the outer cylinder 2 and the inner cylinder 3, and a main reforming chamber is formed inside the inner cylinder 3. The inner cylinder 3 and the oxidizing air feed pipe 14 are each composed of two groove-shaped metal plates 3a and 14a facing each other, respectively, provided that the groove-shaped metal plates 3a and 14a each has flanges 3b and 14b, respectively, and that the flanges 3b and 14b of the groove-shaped metal plates 3a and 14a, respectively, composing the inner cylinder 3 and the oxidizing air feed pipe 14 are quadruply attached and fixed to each other by brazing.
