Abstract:
1. A manufacturing method of a chip-type composite electronic component comprising the steps of: forming an inductor characteristic sheet by laminating a ceramic layer having an internal coil conductor; forming a thermistor characteristic sheet having a predetermined resistance-temperature characteristic by laminating a plurality of ceramic layers, each of at least two adjacent ceramic layers of the plurality of ceramic layers includes an internal electrode, wherein the internal electrode of one of the at least two adjacent ceramic layers extends from a central portion to a first edge of the ceramic layer, and the internal electrode of the other of the at least two adjacent ceramic layers extends from a central portion to a second edge of the ceramic layer that is opposite to the first edge; forming a compound multilayer body by adhering the inductor characteristic sheet and the thermistor characteristic sheet by pressure with a diffusion-prevention layer sandwiched therebetween; baking a compound multilayer body; forming external electrodes on an end surface of a compound multilayer body in which at least one end part of an internal coil conductor and at least one end part of one of said internal electrodes are exposed.
