A deformed nail corrector for correcting a deformed nail is provided that includes: a first elastic wire which has one end portion thereof fixed to one edge of the deformed nail in a width direction a second elastic wire which has one end portion thereof fixed to the other edge of the deformed nail in the width direction and a binding means which binds the first and second elastic wires to each other and is slidable along the first and second elastic wires in a bound state. The first and second elastic wires are brought into a state where the first and second wires are deformed along the deformed nail with the first and second, elastic wires being in a corrector mounting state where the first and second elastic wires are bound to each other by the binding means.
