<P>PROBLEM TO BE SOLVED: To provide an electronic circuit capable of reducing deterioration in a propagation characteristic of a signal due to the effect of a metallic flange and a conductor wall of a connector even when a conductor line formed on an upper side of a board is connected to the connector or passes through a through-hole provided to the conductor wall. <P>SOLUTION: The electronic circuit is provided with the board comprising a dielectric body, the conductor line provided to an upper side of the board, a coaxial connector connected to an end of the conductor line in a signal propagation direction, and the conductor wall to which the connector is fitted, and the conductor line is characterized in that the line width of the conductor line is gradually narrower from a prescribed position than a unique line width determined by a setting impedance of the conductor line as the conductor line approaches the end. <P>COPYRIGHT: (C)2007,JPO&INPIT |
