PROBLEM TO BE SOLVED : To provide barium sulfate having excellent performance in UV screening, lubrication, adhesion, soft focus etc., developed by investigating functions of barium sulfate doped with a specific amount of a rare earth element. SOLUTION : The rare earth doped barium sulfate is barium sulfate doped with a specific amount of a rare earth element, and is represented by the general formula (BaXM1-X)SO4, where M is a metal element and 0.5≤X<1.
