PROBLEM TO BE SOLVED: To detect an object to be detected, by a compact and highly sensitive magnetic impedance effect sensor, when magnetically detecting it by relative moving between the object to be detected and a magnetic sensor. SOLUTION: This magnetic impedance effect sensor has the first magnetic field detecting means for outputting an output difference between a pair of magnetic impedance effect elements 1a, 1b juxtaposed in positive angle +αof direction with respect to a reference line, the second magnetic field detecting means for outputting an output difference between a pair of magnetic impedance effect elements 1a', 1b' juxtaposed in negative angle -αof direction with respect to the reference line, and an adding means for superimposing the output from the first magnetic field detecting means and the output from the second magnetic field detecting means.
