ABSTRACT:
A composite electronic component containing at least two circuit elements including an inductor. The composite electronic component comprises a component body including a laminated body of a plurality of non-conductive layers, an inductor electrode formed between either two adjacent non-conductive layers of the laminated body, a capacitor electrode formed between another two adjacent non-conductive layers of the laminated body, two shield electrodes formed on both surfaces of the laminated body, one of the shield electrodes being opposed to the capacitor electrode to constitute a capacitor, a frequency adjusting capacitor electrode which is formed outside at least one of the shield electrodes through a non-conductive layer and has a smaller area than the capacitor electrode, and a non-conductive protect layer, formed of a non-malleable material, for covering an outer surface of the frequency adjusting capacitor electrode and is to be trimmed along with the frequency adjusting capacitor electrode for frequency adjusting; and at least two connecting electrodes including a first connecting electrode connecting the capacitor electrode to the frequency adjusting capacitor electrode and a second connecting electrode connecting the two shield electrodes to each other.
