Abstract: An electronic device package box is mounted with multiple coil components, is mounted on a circuit board, and includes a box unit, and multiple outer and inner connecting pins. The box unit includes inner and outer surrounding walls, a surrounding base wall connected between the inner and outer surrounding walls, and a surrounding space for receiving the coil components therein. The outer connecting pins are mounted to the outer surrounding wall, and each is connected to a corresponding one of the coil components and the circuit board. The inner connecting pins are mounted to the inner surrounding wall, and each is connected to a corresponding one of the coil components and the circuit board.
