PROBLEM TO BE SOLVED: To provide a gas turbine combustor that can be fixed and supported suitably by a casing made of metal, even when the combustor is manufactured by using ceramic materials.SOLUTION: A gas turbine combustor includes: a tubular body 2 which is made of ceramic material and forms a combustion chamber 2a; and jigs 23, 31 (24, 32) made of metal and fitted externally onto an outer circumferential surface 2d of the tubular body 2, wherein the tubular body 2 is connected via the jigs 23, 31 to the casing 8 made of metal which includes the tubular body 2, and the tubular body 2 is fixed and supported in the casing 8. Annular groove parts 22, 30 which are recessed to the inner side from the outer circumferential surface 2d and are joined together in the circumferential direction are disposed on the outer circumferential surface 2d of the tubular body 2, such that the jigs 23, 31 are fitted into the groove parts 22, 30 and the jigs 23, 31 are externally fitted onto the outer circumferential surface 2d of the tubular body 2. |
