Abstract: <P>PROBLEM TO BE SOLVED: To overcome a problem that impedance decreases at a junction between a wiring conductor on a circuit board and a central conductor of a coaxial connector to enlarge reflection loss of high frequency signals and spoil operating properties of a semiconductor element.  <P>SOLUTION: A nonforming part of an internal-layer ground conductor 2' in the circuit board is formed below the region where the central conductor 7c of the coaxial connector 7 is connected to the wiring conductor 2a having a coplanar line structure fitted with ground on the circuit board, and the length of the central conductor 7c projecting inside the frame body 6 from an insulator 7b is under a quarter of the wavelength of a high frequency signal.
