The invention discloses a wide-range eddy current sensor for pipe deformation detection and a manufacturing method therefor. The eddy current sensor comprises a sensor substrate, wherein the bottom ofthe sensor substrate is provided with a groove; a sensor coil which is disposed on the top surface of the sensor substrate, and is used for emitting an induction signal and receiving a detection signal; a packaging cover which is disposed on the sensor coil, covers the sensor coil, and enables the sensor coil to be packaged on the top surface of the sensor substrate; and a signal processing circuit module which is accommodated and sealed in the groove, receives a detection signal obtained by the sensor coil and carries out the signal processing, wherein the section of the sensor coil in a winding plane is shaped like a first rectangle.
