<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive temperature detection device having excellent responsiveness and accuracy of temperature detection. <P>SOLUTION: In this temperature detection device 10, a temperature detection element 11 is equipped in a casing 110 with a substrate 120, the first optical system 131, the second optical system 132, the first Si photodiode 141, the second Si photodiode 142 and a signal processing part 150. The signal processing part 150 inputs a current signal output from each of the Si photodiodes 141, 142, outputs a voltage signal having a value corresponding to the value of the current signal, and includes a sensitivity adjusting means for adjusting the relationship of an output voltage value with an input current value. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
