PROBLEM TO BE SOLVED: To provide a bridge circuit capable of obtaining a stable output regardless of an atmospheric temperature, and a detector using the same. SOLUTION: In a circuit having a Wheatstone bridge circuit in which four resistors 1-4 are connected so as to form a quadrilateral, for outputting unbalance of voltages of the bridge, by the change of a phenomenon to be measured at the part, namely, the objective part to be measured, where a resistor 1, a part of the Wheatstone bridge circuit, is installed, respective voltages between two opposite angles of the Wheatstone bridge circuit are measured, and temperature-corrected output voltages are obtained from the two voltage values, to thereby enable to execute a measurement in which the influence of an atmospheric temperature is removed.
