A task of the present invention is to provide a Ti-Mo alloy material which can be improved in the yield stress at room temperature by the precipitation of an aged omega phase in the Ti-Mo alloy while maintaining large ductility at room temperature, and a method for producing the same. Provided is a Ti-Mo alloy collectively having an Mo content of 10 to 20 mass%, wherein the Ti-Mo alloy has a winding belt-like or swirly segregation portion having a width of 10 to 20 µm in the plane of a backscattered electron image (BEI) or an energy dispersive X-ray spectroscopy (EDS) image of the Ti-Mo alloy, as examined under a scanning electron microscope, in which Mo content is larger than the collective Mo content of the Ti-Mo alloy. When generally observing the entire plane examined, a segregation structure in a swirly form can be observed. Further, provided is the Ti-Mo alloy which has been subjected to aging treatment so that an aged omega phase is precipitated along the segregation portion. When generally observing the entire plane examined, an aged omega phase structure in a swirly form can be observed.
