PROBLEM TO BE SOLVED: To provide a temperature detection circuit for actualizing a temperature detection of high accuracy with a simple structure and an integrated circuit including the temperature detection circuit. SOLUTION: This temperature detection circuit detects temperature by using the temperature characteristics of its elements, and is characterized by having nodes NA and NB each supplied with a current of always the same amplitude from a power source, a diode D3 connected to between the node NA and a ground node, a plurality of diodes D1 and D2 parallel connected between the node NB and the ground node and produced by the same manufacturing process that the diode D3 undergoes, and a comparator 3 for outputting a signal corresponding to a detected temperature according to potential at the nodes NA and NB. |
