Classification: CPC H | IPC H

Claim 4:
5. The circuit board according to claim 1, wherein
the semiconductor device is subject to internal generation of high-frequency current having a frequency of 100 kHz or higher,
an area surrounded by a first projected path is smaller than an area surrounded by a second projected path, the first projected path being depicted by vertically projecting a path of the high-frequency current in the first closed circuit on a virtual plane parallel to the first conductive layer, the second projected path being depicted by vertically projecting a path of the high-frequency current in the second closed circuit on the virtual plane, and
the first closed circuit has an impedance against the high-frequency current lower than an impedance of the second closed circuit against the high-frequency current.
