What is claimed is: 1. A temperature sensor comprising: a housing; a thermo-sensitive element housed in the housing for outputting electric characteristics varying with a temperature, as an electric signal; and a pair of lead wires connected at their one-side ends with the thermo-sensitive element for extracting the electric signal from the thermo-sensitive element to an outside of the housing, wherein at least one of the lead wires extending outside the housing is made of a mixed twisted wire including: first electric wires made of a first conductor containing copper; and second electric wires made of a second conductor having a higher bending resistance and a tensile strength than those of the first conductor; and wherein said mixed twisted wire comprises the first electric wires enclosing the second electric wires. 2. The temperature sensor according to claim 1, wherein each of the lead wires is made of a mixed twisted wire including: first electric wires made of a first conductor containing copper; and second electric wires made of a second conductor having a higher bending resistance and a tensile strength than those of the first conductor. 3. The temperature sensor according to claim 1, wherein the second conductor contains nickel. 4. The temperature sensor according to claim 3, wherein the second conductor is made of stainless steel. 5. A temperature sensor comprising: a housing; a thermo-sensitive element housed in the housing for outputting electric characteristics varying with a temperature, as an electric signal; and a pair of lead wires connected at their one-side ends with the thermo-sensitive element for extracting the electric signal from the thermo-sensitive element to an outside of the housing, wherein at least one of the lead wires extending outside the housing is made of a mixed twisted wire including: second electric wires made of a second conductor containing nickel; and first electric wires made of a first conductor having a lower electric resistance than that of the second conductor wherein the first conductor contains copper; and wherein said mixed twisted wire comprises first electric wires enclosing the second electric wires. 6. The temperature sensor according to claim 5, wherein each of the lead wires is made of a mixed twisted wire including: second electric wires made of the second conductor containing nickel; and first electric wires made of the first conductor having the lower electric resistance than that of the second conductor.
