PROBLEM TO BE SOLVED: To provide a tubular mold for continuously casting a metal which has an improved service life and can prevent local overheating in the mold. SOLUTION: The tubular mold for continuously casting the metal has a double T-shaped cross section in a beam blank form. The internal outline 3 to set up a cross section of a pouring strand is cooled by a cooling water KW, and the cooling water is guided through the cooling tube line 4 inside the mold wall 2. These cooling tube lines 4 have circular cross sections at the time of manufacturing. The internal outline 3 has a rolled shifting portion 6 between wall portions 9 to readjust the flange region 7 and the web region 8 and, on this occasion, the interval A between two cooling tube lines 4 mutually neighboring in these shifting portions 6 is designed so as to be smaller than the interval B inside the remaining wall portion 9.
