Abstract: The present invention provides a wiring structure of high frequency signal wires and a PCB board including the wiring structure of high frequency signal wires. A test part is formed by extending a high frequency signal wire from a connection end connected with a solder pad, and a test window corresponding to a position of the test part is provided on a copper foil which covers the solder pad and the test part, to expose the high frequency signal wire, such that a high frequency signal transmitted via the high frequency signal wire can be directly tested at the test window. Thus, circular test points used in the prior art can be removed, to effectively solve the problem of insufficient space on a PCB; accordingly, lengths of the high frequency signal wires become more precise, so as to ensure a synchronization of transmission of the high frequency signal wires.
