A brake hydraulic pressure control unit includes motors mounted on one end of a hydraulic block so as to be aligned along a vertical direction. Each motor drives one of two sets of pumps. Solenoid valves and an electronic control unit are provided at the other end of the hydraulic block. Half of the solenoid valves and other component parts, which form a first hydraulic circuit, are provided in a vertically elongated area on the left-hand side of the pump mounting portions, and the other half of the solenoid valves and other component parts, which form a second hydraulic circuit, are provided in a vertically elongated area on the right-hand side of the pump mounting portions, with the component parts of each of the first and second hydraulic circuits overlapping each other in the lateral direction.
