| 发明名称 | Stack-type inductor element and method of manufacturing the same | ||
| 摘要 | A stack-type inductor element includes a stack including a magnetic element layer, a coil-shaped conductor pattern provided in the stack, a plurality of first pad electrodes provided on one main surface of the stack, and a plurality of second pad electrodes provided on the other main surface of the stack and symmetric to the plurality of first pad electrodes. The stack is rectangular or substantially rectangular when viewed in a direction of stack of the stack. A first end and a second end of the coil-shaped conductor pattern are electrically connected to two of the plurality of first pad electrodes, respectively, and the plurality of second pad electrodes are all electrically open. | ||
