A dielectric porcelain composition which comprises, as main components thereof, BaO, Nd2O3, TiO2, MgO and SiO2 in a specific ratio, and further comprises, as sub-components thereof, ZnO, B2O3and CuO in a specific ratio. The above dielectric porcelain composition can be surely sintered at a temperature which is low sufficient to allow the use of an electroconductive material such as Ag and an alloy containing Ag as a main component as an inner conductor. Further, the above dielectric porcelain composition is reduced in the change of the resonance frequency thereof by the temperature change, and can have a specific dielectric constant lower than that of a BaO-rare earth oxide- TiO2 based dielectric porcelain composition. From the above, the above dielectric porcelain composition can be suitably used for forming a multi-layered device.
