<P>PROBLEM TO BE SOLVED: To provide a method for producing a group 13 metal nitride crystal, which is an industrially favorable production method, wherein the Li content in an obtained crystal is low. Ž<P>SOLUTION: The method comprises using a solvent as an ionic solvent containing a total of 0.1-14 mol% of at least one halide selected from the group consisting of a sodium halide, a potassium halide, and a cesium halide, and containing a lithium halide, when growing the group 13 metal nitride crystal on a seed 6 in a liquid 9 containing a nitrogen element, a group 13 element, and the ionic solvent.
