PURPOSE:To remove mismatching of a characteristic impedance between a connector inside as well as a connector and an electronic circuit package or a cable by having conductors on flexible boards connected at the one end to respective conductors of an electronic circuit package or a cable and at the other end to respective spring terminals. CONSTITUTION:An electronic circuit package 21 has conductors connected uniformly to conductors 11b, 11c and 12b, 12c of flexible boards 11 and 12 with a characteristic impedance equivalent thereto. No mismatching of the characteristic impedance thus entirely occurs between them. Also, an electronic circuit 22 has conductors connected to the other end of conductors 11b, 11c and 12b, 12c of the flexible boards 11 and 12 via spring terminals 13. No mismatching of the characteristic impedance thus occurs between them, except for a little bit of a mismatching induced in the spring terminals 13. |
