Abstract
A multilayer composite electronic component is provided with an inductor section and a varistor section. The inductor section has a first sintered body consisting of a stack of nonmagnetic layers, and coil conductors arranged in the first sintered body. The varistor section has a second sintered body consisting of a stack of varistor layers, hot electrodes, and ground electrodes. The first sintered body and the second sintered body are integrally fired. A region of the first sintered body sandwiched between the coil conductors and regions of the first sintered body inside the respective coil conductors are comprised of a magnetic material or a nonmagnetic material and contain a ferrite material containing a Cu component in an amount of 0.05 mol % to 2 mol % in terms of CuO.
