PROBLEM TO BE SOLVED : To provide a high-quality rare earth vanadium oxide single crystal showing little decrease in the transmissivity due to generation of a low valence vanadium ion and to provide a method for manufacturing the crystal. SOLUTION : The method for manufacturing a rare earth vanadium oxide single crystal aims to obtain a single crystal to be used as a medium material for laser generation by growing a crystal by a pulling method from a heated source melt of a rare earth vanadium oxide, wherein the power supplied to contribute to heating the source melt is temporarily increased when precipitation of the crystal from the source melt starts so as to suppress the maximum precipitation rate per unit growth area of the crystal.
