Abstract
In an aluminum nitride structure, a plurality of aluminum nitride regions having different purities are integrally formed to satisfy a predetermined positional relationship, and neighboring regions are brought into direct contact with each other to form an abrupt junction therebetween. Therefore, the aluminum nitride structure has anisotropy in physical properties such as a thermal conductivity, a light transmittance, and a strength.
