A master pressure control device of an electric booster sets an upper limit of current supplied to an electric motor in accordance with an operation amount of an input member to a current limit value A when a condition for limiting the driving of the electric motor is satisfied due to a decrease of voltage of a vehicle power source. The master pressure control device sets the upper limit of the current supplied to the electric motor in accordance with the operation amount of the input member to a current limit value B when the condition for limiting the driving of the electric motor is cancelled due to restoration of the voltage of the vehicle power source to normal while a brake pedal is operated. The current limit value B is larger than the current limit value A used when the driving of the electric motor is limited.
