CONTACTOR FOR ELECTRICAL TEST, ELECTRICAL CONNECTING APPARATUS USING THE SAME, AND METHOD FOR MANUFACTURING CONTACTOR
First Claim
1. An electrical test contactor comprising:
- a contactor main body including a plate-shaped attachment portion extending in the up-down direction, a plate-shaped arm portion extending from the lower end portion of said attachment portion at least to one side in the right-left direction, and a plate-shaped pedestal portion projecting downward from the tip end portion of said arm portion;
a contact portion projecting downward from the lower end of said pedestal portion and having the lower end of said contact portion acting as a probe tip; and
a resistor having a higher resistance value than said contactor main body and said contact portion and arranged at said contactor main body so as to heighten the resistance value of said contactor.

11. A method for manufacturing an electrical test contactor having a contactor main body and a contact portion projecting from said contactor main body and having the tip end acting as a probe tip, said method comprising:
-
a first step of forming on the upper surface of a plate-shaped base member a resistor layer made of a highly-resistive conductive material having a higher resistance value than said contactor main body and said contact portion and taking the form of a resistor being as a part of a pedestal portion of said contactor; a second step of forming on said base member and said resistor layer a metal layer made of a highly-hard conductive material having higher hardness than the remaining portion of said pedestal portion and taking the form of another part of said pedestal portion and said contact portion; and a third step of forming on said resistor layer and said metal layer a highly-resilient conductive layer made of a highly-resilient conductive material having higher resiliency than said metal layer and taking the form of the remaining portion of said contactor main body.
