The magnetoresistive detector of the present invention uses magnetoresistive elements for detecting changes in the magnetic field of a moving magnet 3 which changes a magnetic field, wherein bias magnets (21, 22, 23, 24) can be mounted without using positioning jigs, errors in mounting are prevented, and the mounting density of components on a printed circuit board (4) is improved, whereby improved quality and compactness of the magnetoresistive detector can be achieved. For that purpose, the shape and dimensions of magnetoresistive detector elements (11, 12, 13, 14) are made identical to the shape and dimensions of the bias magnets (21, 22, 23, 24), and on the printed circuit board (4), positioning sections (41) for simultaneously positioning the magnetoresistive detector elements (11, 12, 13, 14) and bias magnets (21, 22, 23, 24) are provided.
