ELECTRIC BRAKE DEVICE

The electric brake device includes an electric motor (4), a brake rotor, a friction pad, a conversion mechanism (6), a braking force command section (18a), a braking force estimation section (24), a controller (2), and a power supply device (30). The controller (2) includes: a power determination section (28) to determine whether an amount of remaining power that can be supplied from a power supply device (3) to the electric motor (4) has become equal to or less than a determined value; and a residual pressure cancellation section (29) to cancel a residual pressure of a braking force by driving the electric motor (4) in a direction opposite to a brake pressing direction such that an estimated value of the braking force obtained by the braking force estimation section (24) becomes equal to or less than a set value, when the power determination section (28) determines that the amount of remaining power has become equal to or less than the determined value.
