1. A method for stripping a metal foil of a shielded electric wire, the shielded electric wire including: a wire core, a shielding metal foil configured to surround an outer periphery of the wire core, and a sheath configured to surround an outer periphery of the metal foil, in which the sheath in a predetermined length range is removed from a distal end of the shielded electric wire, and the metal foil exposed to the outside is stripped from the wire core, the method comprising:
a step of inserting, into an electric wire insertion hole of a peeling jig, a portion at the distal end of the shielded electric wire where the metal foil is exposed in a state where a predetermined gap is left between a one-end-surface of the peeling jig on an inlet side of the electric wire insertion hole and a distal end of the sheath;
a step of blowing air into the electric wire insertion hole from an opening on an other-end-surface side of the peeling jig toward the distal end of the shielded electric wire, thereby causing the metal foil at the distal end of the shielded electric wire to expand while being separated from the wire core;
a step of forming a cut from a side in the metal foil exposed to the outside in the predetermined gap between the one-end-surface of the peeling jig and the distal end of the sheath and expanded by blowing the air; and
a step of cutting the metal foil from the cut as a starting point, wherein
in the step of forming the cut from the side of the metal foil, maintaining the predetermined gap between the one-end-surface of the peeling jig and the distal end of the sheath.
