PROBLEM TO BE SOLVED: To provide a bridge circuit which has achieved temperature compensation with a simple configuration, and a detection device.SOLUTION: A bridge circuit 3 comprises: a first output terminal T2a which is provided in a first path from a first power terminal T1a to a second power terminal T1b and outputs a first electric potential V1; a second output terminal T2b which is provided in a second path and outputs a second electric potential V2; a first sensor element GMR-A provided between the first power terminal T1a of the first path and the first output terminal T2a; a fourth sensor element GMR-D provided between the first output terminal of the first path and the second power terminal; a third sensor element GMR-C provided between the first power terminal of the second path and the second output terminal; a second sensor element GMR-B provided between the second output terminal of the second path and the second power terminal; and a first ladder resistor Rcan1 which is provided in the first path and with a resistance element between adjacent nodes. The first output terminal is connected to a node whose electric potential becomes approximately equal at a first and a second temperature.SELECTED DRAWING: Figure 1 |
