PROBLEM TO BE SOLVED : To provide a colored transluscent zirconia sintered compact having a clear color tone and a high transparency even as a fine member, and being excellent in both designability and beauty, and also capable of being obtained easily in an optional shape; and to provide a method for manufacturing the same.SOLUTION : The colored transluscent zirconia sintered compact includes ≥6 mol% and ≤15 mol% of yttria, ≥3 mol% and ≤20 mol% of titania, and at least 4 mol% in terms of oxide of a lanthanoid-based rare earth element, and has a porosity of 1, 000 ppm at highest. The average crystal particle diameter is preferably 60 μm at largest.
