A three-dimensional magnetic bearing sensorincludes a first sensor, a second sensor, and a third sensoreach constituted by a magneto-impedance sensor elementcomprising a magnetic sensitive memberhaving a characteristic changed responsive to an external magnetic field, an insulatorformed to allow penetration of the magnetic sensitive membertherethrough, and an electromagnetic coilmade up of foil-like conductive patternsarranged in adjacent relation on an outer surface of the insulator. The first sensor, the second sensor, and the third sensorare disposed such that directions in which the magnetic sensitive membersin respective sensors have maximum magnetic field detection sensitivities are substantially orthogonal to each other.

An accelerometer for measuring the displacement of a magnet body using magnetic detecting elements is provided, the accelerometer having superior measurement accuracy by suppressing influence of a peripheral magnetic field. The accelerometer has detecting units each having a cantilever which is elastically deformed so as to rotate around a fixed end thereof, a magnet body provided at a free end of the cantilever, and a magnetic detecting head portion disposed outside the rotation region of the cantilever. In order to correct detection signals output from the magnetic detecting head portions, the accelerometer has peripheral magnetic field detecting portions for measuring a peripheral magnetic field acting on the magnetic detecting head portions and the magnet bodies.
