A semiconductor device includes: a detection Hall element for detecting a magnetic field; a temperature monitor Hall element; and a calculation circuit. The detection Hall element has a characteristic, which is almost a same as the temperature monitor Hall element. The detection Hall element is disposed near the temperature monitor Hall element. The detection Hall element outputs a Hall voltage. The temperature monitor Hall element includes a pair of driving signal supply terminals for outputting a temperature monitor voltage. The calculation circuit calculates to cancel a temperature characteristic of the Hall voltage based on the Hall voltage and the temperature monitor voltage.
