Claim 5:
6. A method of manufacturing the isolator according to claim 1, comprising:
forming a first trench in the cladding, in which the first and the second core extending in the first direction is embedded, in such a way that at least a part of the second core is exposed on a side in a second direction that intersects the first direction when viewed from the first and the second core;
embedding a nonreciprocal member in the first trench in such a way that the nonreciprocal member is in contact with at least a part of the core; and
embedding the magnetic body in the cladding and magnetizing the magnetic body in such a way that a magnetic field is generated in a portion where the nonreciprocal member is positioned and a component in a third direction perpendicular to the first direction and the second direction of the magnetic field is greater than any component in directions other than the third direction.
