<p>PROBLEM TO BE SOLVED: To provide a temperature measuring device excellent in measurement accuracy.SOLUTION: A temperature measuring device including a thermopile 7 for detecting infrared rays emitted by a black ceramic 3 and a protective tube 2 for storing the thermopile 7 stores the black ceramic 3 having an abutting surface 3a abutting against a measured object and a radiation surface 3b for emitting heat absorbed from the measured object via the abutting surface 3a as infrared rays in the top end part of the protective tube 2, and stores a convex lens 6 for condensing the infrared rays emitted by the black ceramic 3 toward the thermopile 7 between the black ceramic 3 and the thermopile 7 in the protective tube 2.</p> |
