<P>PROBLEM TO BE SOLVED: To provide a printed circuit board in which degradation of the characteristics involved in the delivery of a high frequency signal to the outside via a connector is avoided inexpensively and precisely without complicating the configuration significantly. <P>SOLUTION: A printed circuit board has a ground pattern provided, on the outer layer thereof, with a pattern used for delivering a high frequency signal to the outside via a connector and being used for grounding a circuit that outputs or captures the high frequency signal. A conductor film connected with the ground pattern is formed at a specific part other than a part with which an insulator, provided in the connector and insulating the central conductor of the connector for a housing, can come into contact, out of the sidewall of the printed circuit board with which the housing of the connector can come into contact in a state where the connector is used for delivery of the high frequency signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
