Embodiment 1
[0118] First, as the main component raw material constituting the dielectric ceramic composition raw material according to the present invention, SiO 2 -K 2 O-B 2 o 3 Glass-like (glass 1: glass transition point 510°C, average particle size 3.3 μm), quartz and amorphous silica. In addition, alumina and K 2 O-CaO-SiO 2 -B 2 o 3 Glass-like (glass 2: linear expansion coefficient is 118×10 -7 / ℃, the softening point is 650℃, and the average particle size is 0.8μm). In addition, as SiO 2 -K 2 O-B 2 o 3 Glass-like and K 2 O-CaO-SiO 2 -B 2 o 3 As the type glass, commercially available glass was used.
[0119] In this way, the above-mentioned raw materials were weighed so as to have the composition shown in Table 1, and wet mixing was performed for 40 hours by a ball mill. After wet mixing, the resulting slurry was dried with a drier to obtain a dielectric ceramic composition.
[0120] (Evaluation 1)
[0121] An acrylic resin-based binder was added to the obtained di...
