Beschreibung
Zusammenfassung:	A sensor device includes a detection resistor having a resistance value changing according to a physical quantity and a reference resistor compared with the detection resistor, the reference resistor is configured by electrically connecting a first resistance circuit and a second resistance circuit. The first resistance circuit includes a first and a second resistive element having positive and negative resistance temperature coefficients, respectively, which are electrically connected. The second resistance circuit includes a third and a fourth resistive elements having a positive and a negative resistance temperature coefficient, respectively, which are electrically connected. The first resistance circuit is configured to generate a first deviation to either the positive or negative side with respect to a temperature change, and the second resistance circuit is configured to generate a second deviation to the side opposite to the positive or negative side where the first deviation is generated.
