Abstract
A circuit board includes a board, an interface formed on the board, a discharge wiring pair formed on the board and having a first discharge wire connected to the interface and a second discharge wire having a second tip portion facing a first tip portion of the first discharge wire with an interval, an electronic component installed in a signal path connected to the interface, a ground path connected to the second discharge wire, and a discharge induction unit configured to induce discharge between the discharge wiring pair by making a current having a frequency based on a voltage waveform of static electricity to be discharged flow more easily in the discharge wiring pair than in the signal path.
Claims9
A circuit board comprising:
- a board;
- an interface disposed on the board;
- a discharge wiring pair formed on the board and including (i) a first discharge wire connected to the interface and including a first tip part and (ii) a second discharge wire including a second tip part facing the first tip part of the first discharge wire with an interval;
- an electronic component installed in a signal path connected to the interface;
- a ground path connected to the second discharge wire;
- and
- a discharge induction unit configured to induce discharge between the discharge wiring pair by making a current with a frequency based on a voltage waveform of static electricity to be discharged flow more easily in the discharge wiring pair than in the signal path,
- wherein the discharge induction unit includes a filter that suppresses passage of a current with a frequency based on a voltage waveform of static electricity and includes a wiring disposed on the board, and
- the filter is disposed on the signal path.
