A hydraulic pressure control device for a continuously variable transmission of a vehicle which a continuously variable transmission mechanism; a stepwise variable transmission mechanism; a shift control means, the hydraulic pressure control device includes: the shift control means including a line pressure control section configured to increase the line pressure to be greater than the line pressure before a generation of an oil vibration when the oil vibration is generated in at least one of actual hydraulic pressures of the primary pressure and the secondary pressure, and the line pressure control section being configured to continue the increase of the line pressure until the shift of the stepwise variable transmission mechanism is finished when the stepwise variable transmission is shifted in a state where the line pressure is increased.
