<p>PROBLEM TO BE SOLVED: To provide a high frequency connection line, capable of measuring impedance over all connection regions, with characteristic impedance matched over all signal routes after connection.SOLUTION: The high frequency connection line includes a plurality of substrates having formed signal lines 50. By the interconnection of the signal lines 50 of respective substrates 11, 12, 13, 14 at end parts, high frequency signals are transmitted with first characteristic impedance, to form high frequency connection lines for inputting and outputting the high frequency signals from/to both ends of the plurality of substrates. In each substrate 12, 13, 14, the end part of the signal output side connected to another substrate is configured to have second characteristic impedance capable of measurement by a measuring instrument connected to one end part of the output side. On the end part of the signal input side connected to another substrate, characteristic impedance after connected to the end part of the signal output side of the other substrate, having the second characteristic impedance, has third characteristic impedance higher than the second characteristic impedance and substantially coincident with the first characteristic impedance.</p> |
