PURPOSE: To reduce the manufacturing cost, by matching each part of a center conductor to the highest tuning frequency band and narrowering the width of the vertical section for lower tuning frequency band, in the center conductor used for a UHF tuner.

CONSTITUTION: A center conductor 1 used for a UHF tuner is provided with a folded part 2 at one end of a horizontal part 3, and the other end is provided with a vertical section 4, and the vertical section 4 is provided with a folded part 6 and a leg 5 fitted to the base. To change the characteristic impedance and the line length, it can only be made by changing the width of the vertical section 4, and the length of the horizontal part 3 and the folded part 6 is also changed by changing the width of the vertical part 4. Thus, in a manufacturing process, the size is matched to the highest tuning frequency band in which the width of the vertical part 4 is widest, and the width of the vertical part 4 is cut off in narrow size for lower turning frequency bands, allowing to reduce sharply the number of metal molds.
