Abstract: PROBLEM TO BE SOLVED: To provide a dielectric device that is provided with a dielectric layer, having less residual strain and higher characteristics. SOLUTION: The dielectric device 10 is provided with a substrate 11 and a dielectric layer 13. A layered low-density part 13c is formed, between a substrate-side surface 13a as a surface on the side of the substrate 11 and an outer electrode-side surface 13b as an opposite surface to the substrate-side surface 13a, in the dielectric layer 13.

Abstract: The present invention relates to a method for manufacturing "a fired ceramic body including a metal wire in its inside", In the manufacturing method, the metal wire (a coil 11) is placed in a mold 21, and then, "a ceramic slurry having a heat-gelling characteristic or a thermoset characteristic" is poured into the mold. Subsequently, the ceramic slurry is dried and hardened to form a ceramic-compact-before-fired, and then, the ceramic-compact-before-fired is fired. In this firing process, a degreasing of the ceramic compact is firstly performed, and thereafter, a temperature of the ceramic compact is increased up to "a second temperature at which the metal wire is softened and the ceramic compact is fired" at a second temperature increasing rate. The second temperature increasing rate is set at such a rate that "a shrinkage ratio of the ceramic compact when the temperature of the ceramic compact reaches the second temperature is smaller than or equal to a predetermined threshold shrinkage ratio". That is, the rate is set such that the softening of the metal wire starts before the substantial firing/sintering of the ceramic compact starts.
