PROBLEM TO BE SOLVED: To provide a multi-terminal structure for measuring the impedance capable of coping with a narrow measured part, and exercising the characteristic of high strength. SOLUTION: A flexible shaft body 11 is formed by twisting two conductive metallic wires 14, 14 respectively coated with insulating layers 22, a tip part 12 of the flexible shaft body 11 is formed as an independent contact end 15 for the measured part, by respectively exposing a tip of each metallic fine wire 14 from the insulating layer 22 while keeping the mutually insulated- condition, and a rear end part 13 is formed as a connection end 16 for a lead wire 31, by respectively exposing a rear end face 14a of each metallic wire 14 from the insulating layer 22 while keeping the mutually insulated-condition.
