摘要： The invention provides an electronic device comprising a first metal layer containing a first metal converted into an oxide upon firing in an oxidizing atmosphere and a second metal layer formed by firing of a second metal particle containing a metal that is not oxidized upon firing in an oxidizing atmosphere, with an intermediate oxide layer interleaved between these two metal layers. The intermediate oxide layer contains an oxide of the first metal contained in the first metal layer. Preferably, the second metal particle contained in the second metal layer is dispersed in the intermediate oxide layer. A uniform oxide layer is obtained at a simple step, and the resistance value provided by the oxide layer is easily controllable with high precision. It is thus possible to achieve an electronic device in which the bonding strength of the oxide layer with respect to the other metal-containing layer is improved with an improvement in the bonding strength with respect to lead wires.

摘要： A production method for a dielectric porcelain composition having at least BaTiO3 as a main component, a second subcomponent represented by (Ba,Ca)x SiO2+x(x=0.8 to 1.2) and other subcomponents. The main component and at least part of the other subcomponents (excluding the second subcomponent) are mixed together to prepare pre-calcination powder which is then calcinated to provide calcinated powder. At least the second subcomponent is mixed with the calcinated powder to obtain a dielectric porcelain composition where ratios of respective subcomponents to BaTiO3 as the main component are to be specified molar ratios. A monolithic ceramic capacitor can be obtained which can satisfy, even in the case of an ultra-thin dielectric layer as thin as up to 4 mu m, both X7R characteristics (EIA Spec.) and B characteristics (EIAJ Spec.) that are capacity temperature characteristics, and which is small in capacity change with time in a dc electric field, long in acceleration life of insulation resistance and small in capacity reduction under a dc bias.
