Disclosed is a torque sensor apparatus for a vehicle, which may prevent a reduction in the sensing performance caused by an external magnetic field. The torque sensor apparatus for a vehicle according to one aspect of the present invention comprises: a rotor unit which rotates by being connected to any one of an input shaft or an output shaft; a stator unit which is disposed to face the rotor unit, and rotates by being connected to the remaining one of the input shaft or the output shaft; a first measurement unit which has a first measurement member, and measures a change in a magnetic field according to a relative rotation shift of the rotor unit and the stator unit; a third measurement member which is disposed on the same substrate as the first measurement member, and measures the change in an external magnetic field when the external magnetic field is applied; and an amplification unit which is disposed on the substrate, and amplifies the difference in measurement values of the first measurement unit and the third measurement member.
