PROBLEM TO BE SOLVED: To provide a strong dielectric ceramic with a core-shell structure by adding a shell material to a core material and sintering them, having stable high temperature range property capable of maintaining variation of dielectric constant in ±15% even under a temperature condition of 150°C or more as the core material is tungsten bronze type oxide, and capable of being used for a capacitor or the like for onboard or aerospace requiring high temperature range property.SOLUTION: There is provided ceramic G with a core-shell structure by adding a shell material M to a core material S and sintering them, where the core material is tungsten bronze type oxide.SELECTED DRAWING: Figure 2 |
