PROBLEM TO BE SOLVED : To provide a method for manufacturing a Faraday rotator which is excellent in temperature characteristics and showing rectangular hysteresis, and a Faraday rotator. SOLUTION : In a bismuth-substituted rare earth iron garnet single crystal grown by the liquid phase epitaxial method which is shown by chemical formula Tb3-x-yHoxBiyFe5-zGazO12 (0.4≤x≤0.7, 1.1≤y≤1.3, and 0.6≤z≤0.75 in the formula), by making the crystal growth temperature to be ≥870°C and ≤950°C, a temperature characteristic of ≤0.075 (deg/°C) is attained.
