Abstract: A laminated coil component includes: an element body having a first surface and a second surface facing each other in a first direction; a coil unit formed by laminating a plurality of coil conductors in a second direction orthogonal to the first direction inside the element body; a first lead-out conductor; and a second lead-out conductor. A first coil conductor adjacent to the first lead-out conductor in the second direction includes a first side portion extending along the first surface, on a first surface side. A second coil conductor adjacent to the second lead-out conductor in the second direction includes a second side portion extending along the second surface, on a second surface side. The first side portion has a larger line width than other side portions of the first coil conductor and the second side portion.

Abstract: An electronic component has an element body; and an external electrode having a main body portion covering at least the second surface and a first wrapping-around portion wrapping around the third surface in the element body. The wrapping-around portion of the external electrode has a first part having a first distance, a second part having a second distance, a third part having a third distance, a fourth part having a fourth distance, and a fifth part having a fifth distance in the second direction in order from one side to the other side in the first direction. The second distance is longer than the first distance and the third distance. The fourth distance is longer than the third distance and the fifth distance.
