PURPOSE:To provide a molten metal-measuring device and a measuring apparatus using the device which can be used a plurality of number of times thereby restricting measuring cost for one measurement, with showing favorable responding characteristics at the measuring time. CONSTITUTION:A thermocouple for measurement is installed in a molten metal measuring device 10. The outside of the device 10 is covered with a ceramic protecting tube 11 having a closed front end part. The front end part of the protecting tube 11 is exposed and coated with a cermet or ceramic heat buffer tube 12. |
