Zusammenfassung:	A method of manufacturing a gas sensor includes a step of preparing an assembly including a sensor element, a metal cylindrical body through which the sensor element penetrates in an axial direction, and a protection cover that is attached to the cylindrical body and that covers one end side of the sensor element. The method also includes steps of arranging a coil in a periphery of at least a portion of the cylindrical body at the same side as the other end of the sensor element with respect to the protection cover to avoid the protection cover of the assembly, induction heating the portion of the cylindrical body where the coil is arranged in the periphery by applying current to the coil, and hence removing oil adhering to the portion.
