To provide a hydraulic control device which can have enhanced layout properties. The hydraulic control device according to the present invention is provided with a stroke simulator unit and a hydraulic unit. The stroke simulator unit is provided with: a stroke simulator for generating a reaction force to a brake pedal operation, the stroke simulator being separate from a master cylinder for generating hydraulic pressure in response to a brake pedal operation; a simulator connection fluid channel having one end side and another end side, the one end side of the simulator connection fluid channel being connected to the stroke simulator; and a simulator connection port provided to the other end side of the simulator connection fluid channel. The stroke simulator unit is attached to the hydraulic unit. The hydraulic unit is provided with a unit connection port connected to the simulator connection port and overlapping with the simulator connection port as viewed from the axial direction ofthe simulator connection port, and a fluid channel connected to the unit connection port. The hydraulic unit causes hydraulic pressure to be generated in a wheel cylinder of a rolling stock via the fluid channel.
