Abstract

This invention is a laminated electronic part and its manufacturing method. This laminated electronic part can prevent the disconnection between a via conductor and a coil electrode. There are multiple coil electrodes 8 combining together to form a coil L. Multiple magnetic body layers 4 and multiple coil electrodes 8 are laminated together to form a laminated body 2. A contacting part C connects multiple coil electrodes 8; furthermore, the contacting part C has a shape with an end's area that is greater than the other end. External electrodes are formed on the surface of the laminated body and is connected to the aforementioned coil. The length of coil electrodes 8a is longer than the length of coil electrodes 8f. The coil electrodes 8a connecs to a contacting part B1 through one of the aforementioned ends.
