Abstract: To prevent the occurrence of a short-circuit failure through a magnetic body layer. A coil component includes interlayer insulating films and conductor layers which are alternately stacked on a magnetic body layer. The conductor layers respectively have coil patterns, terminal patterns which are provided at positions overlapping a terminal electrode, and terminal patterns which are provided at positions overlapping a terminal electrode. The terminal patterns are connected to the terminal electrode, and the terminal patterns are connected to the terminal electrode. The terminal pattern is insulated from the terminal electrode. This can prevent a short circuit failure between a coil pattern or terminal pattern and the terminal pattern through the magnetic body layer.
