Abstract
A method of producing an electronic device including a dielectric layer includes a dielectric ceramic composition containing a main component expressed by a formula of {(Sr Ca )O} .(Ti Zr )O , wherein x fulfills 0≦x≦1.00 and y fulfills 0≦y≦0.20, and producing said dielectric ceramic composition by using a material expressed by a formula of {(Sr Ca )O} .(Ti Zr )O wherein the mole ratio m′ fulfills m′<m. It is possible to produce an electronic device, such as a chip capacitor, having excellent resistance to reducing during firing and excellent capacity-temperature characteristics after firing, wherein the insulation resistance is hard to be deteriorated particularly when made to be a thin layer and defect rate of the initial insulation resistance is low.
