Abstract
A common-mode choke coil includes first to third spiral coils, in which the diameters of coil portions are substantially the same and the axes of the coil portions are aligned collinearly. Extended portions of the first and second coils have a flectional pattern and connect coil portions located at substantially the center in the longitudinal direction of sheets and input/output electrodes. The junctions of the extended portions and the coil portions have a folded configuration. Accordingly, the number of turns and the line length of the first coil are the same as those of the second coil.
