摘要:
A group of magnetic sheets are stacked and connected via through-holes, on each of which magnetic sheets a circling pattern having connection parts at its corners and ends is formed to form a spiral coil pattern. Leader patterns each have a leader part formed at a position not overlapping with the circling parts of the coil pattern and connected to an external terminal electrode, as well as two connection parts that continue to the leader part and are formed at positions corresponding to the connection parts of the circling patterns, together with a cutout formed between the two connection parts. Magnetic sheets with the leader patterns are provided at the top and bottom of the laminate forming the coil pattern. The multilayer chip inductor can suppress decrease in core area caused by displacement due to the stacking.
