description	Provided are crystal oriented ceramics in which the crystal axis is oriented in one direction, and a method capable of producing the crystal oriented ceramics without any complicated processes. That is, provided are: a method for producing crystal oriented ceramics by contacting a first layer mainly comprising La2SiO5 and a second layer mainly comprising La2Si2O7 to form a bonded interface, then heating the result at a predetermined temperature such that lanthanum silicate having an apatite-type crystal structure is generated in the vicinity thereof, and the c axis of the crystals is oriented in a vertical direction to the original bonded interface; and the crystal oriented ceramics obtained by the production method. La présente invention concerne des céramiques à orientation cristalline dans lesquelles l'axe cristallin est orienté dans une direction, et un procédé permettant de produire les céramiques à orientation cristalline sans aucune opération compliquée. Autrement dit, l'invention concerne : un procédé de production de céramiques à orientation cristalline par mise en contact d'une première couche comprenant essentiellement du La2SiO5 et d'une seconde couche comprenant essentiellement du La2Si2O7 pour former une interface de liaison, puis chauffage du résultat à une température prédéfinie de sorte que du silicate de lanthane ayant une structure cristalline de type apatite est généré à proximité, et l'axe c des cristaux est orienté verticalement par rapport à l'interface de liaison initiale ; et les céramiques à orientation cristalline obtenues par ce procédé de production.
