PROBLEM TO BE SOLVED: To provide a magnetic garnet single crystal, where occurrence of crystal defect is suppressed and to provide a Faraday rotator improved in quenching ratio, related to a magnetic garnet single crystal and a Faraday rotator using it. SOLUTION: A magnetic garnet single crystal is used, which is grown by a liquid-crystal epitaxial growth method and is represented by a general expression BiaPbbA3-a-bFe5-c-dBcGedO12. Where A is at least one kind of element selected from among Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, B is at least one kind of element selected from among Ga, Al, Sc, Pt, and Si, and 0<a<3.0, 0<b<=2.0, 0<=c<=2.0, 0<d<=2.0.
