PROBLEM TO BE SOLVED: To provide a super magnetostrictive hydraulic pressure generating device and a super magnetostrictive hydraulic pressure pump system provided with the device enabling miniaturization and weight reduction of the device, and more efficient use thereof. SOLUTION: The super magnetostrictive hydraulic pressure generating device is provided with pressurized reservoir chamber in an outer circumference zone of the super magnetostrictive drive part in a same housing in which a super magnetostrictive drive part including a super magnetostrictive element changing volume by magnetic force and a drive coil generating magnetic force by excitation to change volume of the super magnetostrictive element, and a pump part including a plunger piston reciprocated in a cylinder with accompanying volume change of the super magnetostrictive element and discharging working fluid from a pressurized reservoir are arranged, and is provided with a communication structure to make at least the drive coil under a condition where the same is dipped in oil from the pressurized reservoir between the pressurized reservoir chamber and the super magnetostictive drive part. The super magnetostrictive hydraulic pressure pump system is provided with an output mechanism and a solenoid valve connected to the generating device and a control mechanism driving and controlling the generating device and the solenoid valve.
