PURPOSE:To improve problems such as contacts between connection conductors due to deformation or mismatching of connection conductors due to a discontinuity in characteristic resistance in connection of a chip and a board. CONSTITUTION:A ground conductor 4 is formed inside an inductor which surrounds a chip 1, and signal conductors 5 outside, where the inductor 3 is sandwiched by the ground conductor 4 and the signal conductors 5. |
