A printed wiring board includes a digital circuit, an analog circuit, and a power supply path that is disposed on an insulating layer between the digital circuit and the analog circuit. A plurality of open stub EBG structures are disposed at an end of a bridge section in a power supply plane. The open stub EBG structure is an open stub state whose one end is connected to the power supply path and other end is in an open state.

Printed wiring board and method of producing the same

A printed wiring board includes a digital circuit, an analog circuit, and a power supply path that is disposed on an insulating layer between the digital circuit and the analog circuit. EBG unit cells are disposed on a boundary between the digital circuit and the analog circuit one dimensionally or two dimensionally and periodically, and an interdigital electrode is formed. A magnetic body film is formed over the printed wiring board, partially formed on the EBG unit cells, or formed avoiding the EBG unit cells.
