HYDRAULIC PRESSURE CONTROLLER

A hydraulic pressure controller includes: a hydraulic pressure control mechanism including a brake control valve for controlling a hydraulic pressure of a brake fluid; and a control substrate including a brake control circuit that controls an operation of the brake control valve. The control substrate includes a suspension control circuit that controls an operation of a suspension control valve for controlling a damping force of a suspension of the vehicle, a first relay that enables energization between the brake control valve and a power supply, and that shuts off energization between the brake control valve and the power supply, and a second relay that enables energization between the suspension control valve and the power supply, and that shuts off energization between the suspension control valve and the power supply.
