PROBLEM TO BE SOLVED: To provide a temperature characteristic measuring device capable of measuring a temperature characteristic accurately in a short time. SOLUTION: A tunnel kiln 1 is controlled to have a desired temperature profile by using a temperature control device 3. A conveyance means 2 is operated after arranging a measuring object 6 thereon, and a temperature profile inside the tunnel kiln 1 is stabilized. A temperature sensor 7 is arranged on the conveyance means 2 and conveyed inside the tunnel kiln 1. Simultaneously, the temperature profile inside the tunnel kiln 1 is measured by using a temperature measuring means 4, and a resistance value measurement position in the tunnel kiln 1 is decided from the result. The conveyance means 2 where the measuring object 6 is arranged is operated at a prescribed speed, when passing through the tunnel kiln 1, a resistance value on the resistance value measurement position is measured by using a resistance value measuring means 5.
