| 发明名称 | Electronic component with coil, method for manufacturing the same and power supply module | ||
| 摘要 | An electronic component includes a circuit board that includes a ground terminal connected to a ground potential, a coil component that is assembled on the circuit board, the coil component includes a T-shaped core and an air-core coil, a ground connection electrode that is assembled on the circuit board next to the coil component and that is connected to the ground terminal, and a mixture of a metal composite magnetic material and a resin that is formed on the circuit board and that covers the coil component and the ground connection electrode as a package. A part of the ground connection electrode is exposed outside the mixture. | ||
