PURPOSE: To obtain a fixing structure for magnetic sensor which can be protected against cracking due to application of stress to the insulating board while eliminating disconnection at the electrode part. CONSTITUTION: The fixing structure for magnetic sensor comprises a reluctance element 3 mounted on an insulating board 1 provided with a resistor pattern, and a holder 5 for the reluctance element 3, wherein the holder 5 is secured to a circuit board 6 and the electrode part of reluctance element 3 is soldered 8 directly with a terminal 7 on the circuit board 6. The circuit board 6 is made of a resin material and a reinforcing board 9 is applied to the rear of the position where the holder 5 is secured. The reinforcing board 9 has coefficient of thermal expansion substantially equal to that of the insulating board 1 mounting the reluctance element 3. |
