The invention discloses a hydraulic supply device. The hydraulic pressure supply device includes: a motor including a stator and a rotor; a motion conversion mechanism for converting the rotational motion of the rotor into linear motion; a piston which is connected to the motion conversion mechanism and performs linear motion; a housing including a cylinder in which the piston is disposed so as to be linearly movable, and a guide which extends in the longitudinal direction of the cylinder and is inserted inside the piston, and in which a fluid pressurized by the piston is disposed in a space between the inner peripheral surface of the cylinder and the outer peripheral surface of the guide; a first magnet disposed in the piston; and a first magnetic sensor that is disposed on the guide and detects a change in the magnetic field of the first magnet due to the rectilinear motion of the piston.
