<P>PROBLEM TO BE SOLVED: To provide a magnetic sensor device which is free from input signals getting unsettled, has little variation in amplification and is excellent in temperature characteristics. Ž<P>SOLUTION: The magnetic sensor device includes a detection circuit 10 having a plurality of MR elements connected like a bridge, whose resistance values vary depending on a direction of an applied magnetic field to output a detection signal depending on a change in the resistance value from an output pad 111 or the like, and an amplification circuit 20 having an input pad 221 or the like to which the detection signal is input to amplify and output the input detection signal, wherein the output pad 111 or the like and the input pad 221 or the like are connected via double wire bonding.
