PROBLEM TO BE SOLVED: To provide a premixed tubular flame burner that can achieve a compact combustor for reducing NOx. SOLUTION: The premixed tubular flame burner eccentrically introduces an air-fuel mixture M from a plurality of slits 3 opened along a tube axis direction of a cylindrical combustor chamber 2 into the combustor chamber, and rotates and combusts the combustor chamber, wherein the slits 3 are communicated around an outer circumference of the combustor chamber 2, an annular circumferential circuit 4 having a width in the tube axial direction of the combustor chamber 2, the length of which is equal to or longer than an opening in the tube axis direction of the combustor chamber 2 of the slits 3, and a mixer 5 for mixing fuel with air is provided so as to introduce the air-fuel mixture M to the circumferential circuit 4 in the same direction as a rotation direction in the rotation combustion in the combustion chamber 2.
