摘要： PROBLEM TO BE SOLVED: To provide a long hollow ceramic member wherein an alumina crystal has high orientation in the length direction, the strength in the length direction is high, and the weight is reduced due to a hollow shape, and a manufacturing method thereof. SOLUTION: The long hollow ceramic member 1 is made of an alumina sintered body. In the long hollow ceramic member 1, I 006 /(I 006 +I 300 )×100, calculated with a peak intensity 18 of (006) plane of Miller index expression obtained by a measurement of an X-ray diffraction method for the plane parallel to the length direction as I 006 and the peak intensity 19 of (300) plane as I 300 , is 7 or more. Since the orientation of the alumina crystal is high even in the inside, the strength to a bending stress in the vertical direction to the length direction can be increased and the weight can be reduced due to the hollow shape.
