PROBLEM TO BE SOLVED: To provide a means for performing quickly and simply operation confirmation of a detection element and a signal processing circuit in a biosensor chip. SOLUTION: This biosensor for analyzing a measuring object by measuring the amount of magnetic body particles bonded to a magnetometric sensor is equipped with the magnetometric sensor formed by arranging a plurality of Hall elements for outputting an output value corresponding to the intensity of a detected magnetic field in a two-dimensional form comprising X rows and Y columns (X and Y are natural numbers, hereinafter the same). At least one element among the plurality of Hall elements is used as a checking Hall 14 element having an output characteristic different from other Hall elements. COPYRIGHT: (C)2007,JPO&INPIT
