PROBLEM TO BE SOLVED: To improve accuracy of an arranging position of an insulated wire, and to prevent damage of the insulated wire by fastening and arranging the inside surface of the U-shaped top part of the insulated wire in a frictional limit of a frictional material, and surrounding at least the inside surface of the U-shaped top part by a probe main body. SOLUTION: In a state of allowing the inside surface of the U-shaped top part 24 of an insulated wire 20 to abut to the upper surface of the electric wire guide part 14 of a probe main body 10 one of contractive tubes 30 fitted around the respective parts of the insulated wire 20 projecting from the rear end of the probe main body 10 is fitted around small projections 15, 15 to be fastened to the contractive tubes 30. Thus the inside surface of the U-shaped top part of a conductor 21 can be accurately set to a wire W being a frictional limit position of a frictional material 42, and the tip more than this wire W, in other words, the outer periphery of the frictional material 42 side top part 24, that is, the outside surface side more than the U-shaped top part is constituted so as to be surrounded by the tip of the probe main body 10 to thereby reduce a danger of damaging the U-shaped top part 24 at handling time or by a stepping stone.
