Abstract
A unitary composite electronic component having both a filter function and a surge voltage absorption function is arranged to have a varistor laminated body laid on top of an inductor laminated body and a capacitor laminated body, or at least one of them, and is baked so as to be integral in order to construct a laminated body. The unbaked varistor laminated body is provided with varistor electrodes, and the unbaked inductor laminated body is provided with an inductor conductive line and the unbaked capacitor laminated body is provided with capacitor electrodes, respectively. The above-described laminated body is provided at the sides thereof with external electrodes for properly connecting the above-described varistor electrodes with the inductor conductive line and the capacitor electrodes to obtain a composite electronic component having both a filter function and a surge voltage absorption function.
