PURPOSE: A connector connecting board structure for high speed is provided to cost-effectively be manufactured by combining a board with a signal inlet groove and a ground groove, and a common connector. CONSTITUTION: A ground groove(20) with a plating inner circumference(21) is formed on a board(10). A line insertion hole(30) passes through the vertical direction of the center part in the ground groove to form a plating inner circumference(31). A via-hole(90) is in connection with a coated plating layer. The first pattern(51) of a metal layer connects a signal inlet groove(80) and the upper side of the light insertion hole. A base pattern(60) is composed of a second pattern(52) of the metal layer connecting the via-hole and the upper side of the ground groove.
