<p>PROBLEM TO BE SOLVED: To lower desired wiring impedance by forming grips of a conductive metal member at positions corresponding to desired electrodes and inserting and holding a circuit board by the grips to electrically connect desired electrodes to corresponding grips. SOLUTION: A circuit board 1 is held by grips 12, 13 of a conductive metal member 10 so as to electrically connect the grips 12, 13 to electrodes 6, 7 and the grips 12, 13 are soldered to the electrodes 6, 7. Lead terminals are soldered to electrodes 5, 8. The electrode 7 is electrically connected to the electrode 6 through he metal member 10. Lead terminals are connected to an external ground to lower the impedance of a ground wiring on the circuit board 1 through the metal member 10.</p> |
