To provide an industrially advantageous molybdenum material which is capable of secondary recrystallization at a temperature lower than that of a conventional molybdenum material and which can be converted through the secondary recrystallization into a material that has a structure comprising very large grains with reduced grain boundaries and thus exhibits excellent creep resistance.
When analyzed by X-ray diffraction measurement, this molybdenum exhibits, in at least part of the region corresponding to a sheet-thicknesswise depth of one fifth of the whole thickness from the surface, areas which each contain such a domain where the peak intensities of the (110) and (220) diffraction planes are each lower than the peak intensity of the (211) diffraction plane.
