PURPOSE:To reduce the size and weight of the titled instrument by using a three-terminal type resistor temperature measuring body. CONSTITUTION:A pair of measuring cores 8 are formed by twisting two wires, one of conductors coated with insulating materials 1 is used as a feeding core 9, and (n) pairs of cores 8 and one core 9 are surrounded by a binder 4 through an inclusion 3 and then a sheath is applied to the periphery of the binder 4. A measuring cable is formed by this method. Respective terminals T1, T2 of (n) three-terminal type resistor temperature measuring bodies 6 are individually connected to balance detecting terminals A, A' in respective pairs through (n) pairs of cores 8 (r1, r2) and the terminals T3 of respective bodies 6 are connected to terminals A, A' in respective pairs in common through the core 9 (r3).
