The present invention provides a brake hydraulic pressure controller capable of suppressing retention of air bubbles on a release side of a pump.The brake hydraulic pressure controller includes: a housing; a motor attached to the housing; and plural pump elements, each of which is attached to a recess formed on a side surface of the housing and driven by a motor. Each of the pump elements includes: a suction valve suctioning a brake fluid into a pump chamber; a release valve releasing the brake fluid from the pump chamber; and a channel forming member arranged on a release side of the release valve. The channel forming member includes: a spring chamber accommodating a spring for urging a valve body of the release valve in a closing direction; and a passage communicating between the spring chamber and an outer surface of the channel forming member. The passage in the channel forming member of each of the plural pump elements extends upward from a position including a top portion of the spring chamber in a vertical direction and is connected to the outer surface.
