To provide a hydraulic control unit totally miniaturized by properly arranging the electromagnetic valves having the solenoid coil parts of different sizes.

Two rows each of which has four small electromagnetic valves (PC1 and the like) are mounted in parallel with one another on one surface of a housing H, and two rows each of which has two large electromagnetic valves (SC1 and the like) are mounted in parallel with one another on one surface of the housing H in parallel with the row having four small electromagnetic valves. Further each of four large electromagnetic valves (for example, SC1) is substantially contacted with two small electromagnetic valves (for example, PC1, PC2) adjacent to one another in each row.
