PURPOSE: A transfer sensor and manufacturing method thereof are provided to prevent the shaking of a pendulum sensor unit using the magnetic field between a sub magnet and a compensation magnet, thereby increasing the sensing reliability of the transfer sensor. CONSTITUTION: A pendulum sensor unit(120) comprises a main magnet and a sub magnet. A bracket(110) fixes the horizontal shaft of the pendulum sensor unit. A magnetic sensor(131) is arranged under the pendulum sensor unit. A magnetic field is formed between the main magnet and the magnetic sensor. The compensation magnet is inserted into a bracket by welding. When the pendulum sensor unit returns to an original location, the compensation magnet prevents the shaking of the pendulum sensor unit.
