Claim 10:
11. The balance-unbalance conversion apparatus according to claim 10, wherein:
a cross-sectional thickness of the first impedance matching section remains unchanged, and a cross-sectional width of the first impedance matching section gradually increases in a direction toward the unbalance signal connecting section, so that the cross-sectional area of the first impedance matching section gradually increases in the direction toward the unbalance signal connecting section; and a cross-sectional thickness of the second impedance matching section remains unchanged, and a cross-sectional width of the second impedance matching section gradually increases in the direction toward the ground section, so that the cross-sectional area of the second impedance matching section gradually increases in the direction toward the ground section; or
the cross-sectional thickness of the first impedance matching section remains unchanged, and the cross-sectional width of the first impedance matching section gradually decreases in the direction toward the unbalance signal connecting section, so that the cross-sectional area of the first impedance matching section gradually decreases in the direction toward the unbalance signal connecting section; and the cross-sectional thickness of the second impedance matching section remains unchanged, and the cross-sectional width of the second impedance matching section gradually decreases in the direction toward the ground section, so that the cross-sectional area of the second impedance matching section gradually decreases in the direction toward the ground section.
