PURPOSE: A solenoid current delay circuit of a shift lever is provided to minimize impact vibration and noise generated during solenoid operation by reducing the operation speed of a plunger. CONSTITUTION: A solenoid current delay circuit of a shift lever comprises a first transistor(Q1), a comparator(OP), a first capacitor(C1), and a first resistance(R1). The first transistor switches the current in a solenoid. The comparator compares the driving voltage applied in a solenoid and reference voltage. The comparator turns on/off the first transistor based on the comparison result. The first capacitor and the first resistance apply the reference voltage to the inversion input terminal of the comparator.
