PROBLEM TO BE SOLVED: To provide a tubular flame burner which can be inexpensive and compact while demonstrating characteristics of tubular flame more remarkably. SOLUTION: In the tubular flame burner, mixture of fuel gas and air, or the fuel gas and the air, are eccentrically introduced from a slit 3 opened along a tube axial direction of a cylindrical combustion chamber 2 to be turned/burnt. A flow passage width of an introduction passage 5 for introducing the mixture or the fuel gas and the air to the slit 3 is continuously contracted as it approaches to the combustion chamber 2.
