PROBLEM TO BE SOLVED: To provide a method for manufacturing an oxide single crystal having a composition nearly equal to a stoichiometric composition by a crystal-pulling method using a double crucible. SOLUTION: The method for manufacturing the oxide single crystal utilizes an edge-defined film-fed growth method (EFG method), comprising growing the single crystal by raising a melt by the capillary phenomenon through a slit-like opening part provided at the inside of a die arranged in a crucible accommodating a raw material melt and crystallizing the melt at an upper end opening part of the die. In the method, a melt of the raw material, charged into the crucible so that the single crystal composition becomes the stoichiometric composition substantially, is pulled.
