This invention provides a dielectric ceramic composition which can solve a problem of a conventional composite oxide, consisting of a rare earth element and Si only, that, when it is sintered in a reducing atmosphere to grow crystals, rapidly causes a deterioration in properties such as high-temperature load reliability and the like. The dielectric ceramic composition comprises main phase particles composed mainly of ABO<sub La présente invention porte sur une composition céramique diélectrique susceptible de résoudre le problème lié à un oxyde composite conventionnel, consistant en un élément de terre rare et de Si uniquement, qui, en cas de frittage dans une atmosphère de réduction pour produire des cristaux, provoque rapidement une détérioration des propriétés comme une fiabilité des contraintes à haute température et autres.
