PROBLEM TO BE SOLVED: To provide a birefringent plate and an optical isolator using a crystal which is completely different from a crystal conventionally used as a birefringent plate and which is extremely large in birefringent and can be easily produced. SOLUTION: The birefringent plate 1, 2 consists of a single crystal of PbMoO4 (lead molybdate), K5(BixNd1-x)(MoO4)4 (wherein 0<x<1) or BaLiNb5O15. The optical isolator S is obtained by disposing the birefringent plates 1, 2 on the entrance side and exit side of light of a Faraday rotator 3.
