Abstract: A method of producing a dielectric material by preparing a slurry by mixing a dielectric powder, water, one of an organic-acid metal salt and an inorganic metal salt, and an organic silicon compound, causing the slurry to come into contact with an anion exchange resin to remove an anion derived from the one of the organic-acid metal salt and the inorganic metal salt from the slurry, and drying the slurry to obtain the dielectric material.

Abstract: A composite laminate includes first sheet layers and second sheet layers. The first sheet layers include a first particulate aggregate and the second sheet layers include a second particulate aggregate. Each of internal second sheet layers is disposed between two first sheet layers and two external second sheet layers constitute two main faces of the composite laminate. The thickness of the internal second sheet layers is greater than the thickness of the external second sheet layers. The first sheet layers and the second sheet layers are bonded to each other by penetration of a part of the first particulate aggregate contained in the first sheet layers into the second sheet layers. This configuration can reduce the transverse shrinkage in the firing step of the composite laminate.
