Abstract
Composite electronic including coil, capacitor and intermediate parts, wherein coil part includes coil-conductor and magnetic-layer, capacitor part includes internal electrodes and dielectric-layer, which contains SrO—TiO2 or ZnO—TiO2 based oxide, intermediate part between coil and capacitor parts, intermediate part includes intermediate material layer, which contains ZnO, TiO2 and boron, ZnO contained in intermediate material layer 50-85 parts by mole and TiO2 contained the intermediate material layer 15-50 parts by mole when total content of ZnO and TiO2 in intermediate material layer is 100 parts by mole, content boron in intermediate material layer is 0.1-5.0 parts by weight of B2O3 when total of ZnO and TiO2 in intermediate material layer set to 100 parts by weight, part of ZnO and TiO2 intermediate material layer constitute ZnO—TiO2 compound, which in intermediate material layer is 50 wt % or more when total weight of ZnO and TiO2 in intermediate material layer is set to 100 wt %.
