Abstract

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.
