Therefore, both ground parts 2 and 12 are not damaged. Further, since the ground portion 2 is formed of a flexible member and the portion that holds the ground portion 12 is the constricted portion 7, the ground portion 12 in contact with the constricted portion 7 is further connected to the probe 10. When inserted into the inside, the constricted portion 7 is elastically deformed, so that the insertion can be performed easily, and the signal terminal 14 is connected to the electrode terminal 4.
Can be accurately inserted.
