Magnetic sensor and bill validator using the same |
(57) A highly sensitive magnetic sensor and a bill validator using the magnetic sensor
are disclosed. The magnetic sensor is provided with an artificial-lattice MR (magnetic
resistor) element formed on a board. The artificial-lattice MR element and wiring
terminals, coupled to the artificial-lattice MR element, are integrated in a housing
with resin. Moreover, a magnet is mounted in a hollow at the back of the board in
the housing to provide a plane of artificial-lattice MR element with an auxiliary
magnetic field perpendicularly.
