PROBLEM TO BE SOLVED: To solve the problem that a resonance ascribed to the width of a flat plate of an input/output terminal influences transmission characteristics of high frequency signals to result in that no desired high frequency transmission characteristics could be obtained, and a deformation of a semiconductor package being screwed to an outer electric circuit board, etc., is directly exerted to the input/output terminal to cause cracks in the flat plate. SOLUTION: An input/output terminal 3 is composed of a flat plate 6 of an approximately square dielectric having a line conductor 7 formed from one side to the opposite side on the upside and a vertical dielectric wall 89 bonded to the upside of the flat plate 6 through the line conductor 7. Both sides and the downside parallel to the line conductor 7 of the flat plate 6 are fitted in a groove 4a formed into the upside of a metal base 4. Thus, the terminal 3 is fitted and mounted on the metal base 4 and fitted to a mounting part 9 together with the base 4. |
