Provided is a deformed nail corrector which enables a user to adjust magnitude of an elastic force without spending an extra cost and extra time and efforts.A deformed nail corrector 1A for correcting a deformed nail includes: a first elastic wire 2 which has one end portion thereof fixed to one edge of the deformed nail in a width direction a second elastic wire 3 which has one end portion thereof fixed to the other edge of the deformed nail in the width direction and a binding means 4 which binds the first and second elastic wires 2, 3 to each other and is slidable along the first and second elastic wires 2, 3 in a bound state, wherein one end portion of the first elastic wire 2 is fixed to one edge of the deformed nail in the width direction, one end portion of the second elastic wire 3 is fixed to the other edge of the deformed nail in the width direction, and the first and second elastic wires 2, 3 are brought into a state where the first and second wires 2, 3 are deformed along the deformed nail with the first and second elastic wires 2, 3 being in a corrector mounting state where the first and second elastic wires 2, 3 are bound to each other by the binding means 4.
