PURPOSE:To fix a center conductor in the through-hole of a dielectric substance without soldering it. CONSTITUTION:In the case of packaging a round bar-like center conductor 12 to a through-hole 13 formed on the center axis of a dielectric substance 11, the conductor 12 is cooled by liquid nitrogen or the like to contract it and then inserted into the through-hole 13. The outer diameter of the cooled center conductor 12 is set up so as to be smaller than the inside diameter of the through-hole 13, and in a room temperature state, the conductor 12 is set up so as to be adhered tightly to the blank of the through-hole 13. |
