To provide a fluid pressure control device that can commonalize a circuit configuration effectively in fluid pressure circuits in which kinds and fluid pressures in a working fluid are different from each other.
A fluid pressure control device includes: a first fluid pressure circuit 1L that is operated by a first working fluid having a first fluid pressure; a second fluid pressure circuit 9H that is operated by a second working fluid having a second fluid pressure; a first fluid pressure conversion part 3 that is operated by power from a power source and converts the first working fluid supplied from a first fluid supply part 4 into the first fluid pressure to discharge it; a second fluid pressure conversion part 10M that is operated by a fluid pressure of the first working fluid discharged from the first fluid pressure conversion part and converts the second working fluid supplied from a second fluid supply part 15 into the second fluid pressure to discharge it; a first supply passage that supplies the first working fluid to the first fluid pressure circuit; and a second supply passage that supplies the second working fluid to the second fluid pressure circuit.
