To provide a release wire capable of smoothly responding to both motions of pushing force and pulling force without any problems.

In the release wire comprised of a cylindrical outer tube 1 and an inner wire 2 moving back and forth in the outer tube 1, the inner wire 2 is comprised of a coiled wire 4 winding metal wire in a spiral-shape and a twisted wire 3b, which is inserted through the coiled wire 4, twisting metal wire 3a or a plurality of metal wire 3a. The coiled wire 4 works for pushing force from an operating portion, and the metal wire 3a or the twisted wire 3b works for pulling force.
