1. A magnetic sensor comprising:
a first magnetoresistive strip including a plurality of magnetoresistive elements arranged in a first direction through a plurality of hard magnetic members that apply a magnetic bias;
first and second ferromagnetic films arranged in a second direction crossing the first direction through a first magnetic gap extending in the first direction; and
first and second terminal electrodes,
wherein the first magnetoresistive strip is disposed around the first magnetic gap to be applied with a magnetic field to be detected in the second direction,
wherein one end of the first magnetoresistive strip in the first direction is connected to the first terminal electrode not through another magnetoresistive element applied with the magnetic field to be detected, and
wherein other end of the first magnetoresistive strip in the first direction is connected to the second terminal electrode not through another magnetoresistive element applied with the magnetic field to be detected.
