A shift device includes: a shaft member which can be displaced according to a shift operation of a shift pedal of a vehicle; a housing which can accommodate the shaft member in a displaceable manner and move integrally with the shaft member in a state where the shaft member reaches a displacement end to perform a gear-shifting operation of the vehicle; and a detecting unit for detecting displacement of the shaft member with respect to the housing. The detecting unit includes: an electromagnetic field detection unit in which a transmission circuit which generates an electromagnetic field by supplying a high-frequency signal and a reception circuit which is formed in the transmission circuit and can receive the electromagnetic field generated by the transmission circuit to generate a voltage are formed on a substrate and which is formed along a displacement direction of the shaft member; a shielding portion which is close to the electromagnetic field detection unit at a position corresponding to the displacement of the shaft member and shields the electromagnetic field generated by the transmission circuit of the electromagnetic field detection unit; and a displacement detection unit which can detect the displacement of the shaft member based on a voltage change in the reception circuit caused by shielding of the electromagnetic field by the shielding portion.
