description The invention discloses a magnetic sensor and a mobile information terminal apparatus. The disclosed magnetic sensor includes a substrate having a plane surface and multiple sloping surfaces; multiple soft magnetic films each disposed on a different one of the sloping surfaces and magnetized according to strength of a magnetic field; and multiple detecting devices each disposed on the plane surface, including a free layer and a pinned layer and configured to produce a detection output according to magnetization of the free layer and the pinned layer. Each of the soft magnetic films is magnetically coupled with the free layer of a different one of the detecting devices. The pinned layers of the detecting devices have magnetization directions different from each other.
