PROBLEM TO BE SOLVED: To provide a compact temperature measuring instrument easy to be handled, compared with conventional one. SOLUTION: This temperature measuring instrument 1 is provided with an optical fiber for receiving and transmitting an infrared ray emitted from a measured object surface, the first and second photoelectric transfer elements 13, 14 having spectroscopic sensitivity characteristics different each other, and for receiving the infrared ray to generate an electric signal in response to energy thereof and the spectroscopic sensitivity characteristic, a temperature calculation part for calculating a temperature of the measured object, based on the generated electric signal, a Peltier element 21 having a heat sink electrode 21a and a heat radiation electrode 21b, and a storage container 30 for storing and holding the respective photoelectric transfer elements 13, 14 and the Peltier element 21. The first photoelectric transfer element 13 is arranged in an upper side of the second photoelectric transfer element 14, and receives the infrared ray transmitted by the optical fiber, and passed through a transparent plate 32 of the the storage container 30. The second photoelectric transfer element 14 is arranged on a heat sink electrode 21a surface of the Peltier element 21, and receives the infrared ray transmitted through the first photoelectric transfer element 13.
