A hydraulic pressure braking force generation device is provided with a first control unit for performing control for inhibiting excessive responses in which the input pressure is controlled such that the output pressure is within a first region set using a braking target oil pressure as a reference, a second control unit for performing control for responsiveness in which the increase speed or decrease speed of the input pressure is increased so as to be larger than that in the control for inhibiting excessive responses, to cancel response delay and a switching unit which, on the basis of the state of the braking target oil pressure, switches between the control for inhibiting excessive responses performed by the first control unit and the control for responsiveness performed by the second control unit.
