The electric winch device includes a required braking force estimation section (44) which estimates a required braking force which is a braking force required to stop a free-falling object at a position at an allowable stopping height set by a setting unit; a braking force determination section (50) which determines, out of an operational braking force estimated by an operational braking force estimation section, each of a first braking force to be borne by a braking device and a second braking force to be borne by a braking force which is generated in an electric motor due to consumption of regenerative power; and a control section (52) which causes the braking device to apply the first braking force, which has been determined by the braking force determination section, to a winch drum. The braking force determination section (50) determines the first braking force to be a braking force equal to or greater than the required braking force when, at a time of stopping of the free-falling object, the operational braking force estimated by the operational braking force estimation section (44) is equal to or greater than the required braking force.
