For the twin inductor, it is difficult to design it into a symmetrical structure, and its endpoints need to be configured at specific positions. Therefore, the application scope of the above inductors is limited. Summary of the invention

The second line is arranged in a second area, and the first area and the second area are adjacent to each other at a junction. The connector is arranged in a block adjacent to the junction and not arranged with the first line and the second line, and couples the first line and the second line.

[0004] Therefore, according to the technical content of the present application, the inductor device shown in the embodiment of the present application can effectively utilize the vacant blocks to configure the connection structure, thereby simplifying the connection structure and improving the quality factor.
