Aluminophosphate-metal oxide joined body and production method for same

Provided is an aluminophosphate-metal oxide joined body that exhibits a favorable joined state even for complicated shapes. The aluminophosphate-metal oxide joined body includes a metal oxide that contains a joining surface on part of a surface, and aluminophosphate that is arranged on the joining surface of the metal oxide. An alkaline metal, an alkaline earth metal, or both, are disposed on the joining surface of the metal oxide, and the content ratio of the alkaline metal, the alkaline earth metal, or both, is 0.3-30.0 mass% with respect to all the products disposed on the joining surface of the metal oxide.
