PURPOSE: A resistance measurement device of a solenoid coil is provided to measure resistance of a solenoid coil regardless of temperature and to extract a reference parameter by temperature, thereby operating a proper control pattern suitable for resistance of a solenoid coil. CONSTITUTION: A resistance measurement device of a solenoid coil includes a reference resistor(SR) serially connected to a solenoid coil, a voltage supply unit(20) supplying different voltage to a reference resistor and an MCU(30) calculating resistance of a solenoid coil using the voltage supplied to the reference resistor(SR) by the voltage supply unit and the resistance of the reference resistor.
