PURPOSE: To provide a terminal having satisfactory frequency characteristics in a supper high frequency range, which is used for the transmission line of a spectrum analyzer or a network analyzer as electronic measuring equipment. CONSTITUTION: When a signal in the super high frequency range is inputted to a signal line 1 of a terminal 8 while using a coaxial cable 6 or the like as a transmission line, a GND-Plane A 3 having a ground potential is provided on both sides on the same plane of a circuit board 7 parallelly with a signal propagating direction with the signal line 1 as a center. A resistor 2 is provided to connect those GND-Plane A 3 and signal line 1 on three planes and a grounded coplanar line is formed with a GND-Plane B and plural through holes A5 provided on the rear face of the circuit board. |
