Abstract: In the multi-layer coil component, the via conductor electrically connecting the coil layers adjacent to each other in the stacking direction of the element body protrudes from the coil region toward the side surface of the element body when viewed from the stacking direction of the element body. Therefore, the coil has a concave-convex portion. When a force is applied to the multi-layer coil component from the outside, the force is dispersed in the concave-convex portion of the coil, and thus defects are less likely to occur in the coil than in a coil in which the side of the side surfaces is flat.

When the lead conductor is led out to the end surface of the element body, the lead area can be easily increased as compared with the case where the lead conductor is led out to the side surface of the element body. Therefore, by connecting the coil and the external electrode via the lead conductor, high connectivity between the coil and the external electrode is achieved.
