Abstract: PROBLEM TO BE SOLVED: To provide a connector for signal transmission lines, a signal transmis sion line, and a board by which deterioration in the entire transmission character istic of a network transmission line network can be prevented even when the connector for the transmission line with a characteristic impedance different from the one required for the transmission line exists on the network transmis sion line network. SOLUTION: Transmission line patterns 108 are provided on a flexible cable 100. A land 112 to connect a connection pin 110 of an RJ 45 connector 102 and a land 116 for connection of a connection pin 114 of a transmission line connector 106 are formed on the transmission line pattern 108 and connection pins 110, 114 are connected to the lands respectively by soldering. The width of the transmission line pattern 108 around the connection pin 114 of the transmission line connector 106 is gradually changed toward the connection pin 114.
