PURPOSE: To make connecting work so easy and accurate by joining a cable conductor to a metallic plating layer on a peripheral surface of an adapter body, and also electrically connecting this cable conductor and a connecting conductor piece together.
CONSTITUTION: An adapter body 14 is manufactured after primary molding with easy plating resin and the secondary molding with hard plating resin, respectively. Then, this body 14 is washed clean, roughened and plated, forming a metallic plate layer in a connection wiring part of the easy plating resin exposed on the surface. A socket type pin 11 is inserted into a sluice hole, and the sluice hole plating and this pin 11 are connected by solder 12, manufacturing a connecting adapter in this way. In succession, an external conductor 3 of a coaxial line center 1 is connected to a metallic plate layer 9 and a central conductor 4a to another metallic plate layer 10 with solder 7, 8, respectively. If so, the pin 11 and the conductor 4a are connected together when connecting this conductor 4a to the plate layer 10. With this constitution, connecting work for the conductor 4a can be done easily and accurately, thus reliability is well improvable.
