The first and fourth magneto-resistive elements are connected at respective other ends through a third connecting portion, and the second and third magneto-resistive elements are connected at respective other ends through a fourth connecting portion. Depending on an external signal magnetic field, resistance values of the first and third magneto-resistive elements change in a same increasing or decreasing direction, whereas resistance values of the second and fourth magneto-resistive elements change in an increasing or decreasing direction opposite to the direction of the first and third magneto-resistive elements.
