ABSTRACT:
A method of string an SMA, method of manufacturing the SMA actuator, SMA actuator and apparatus for manufacturing the SMA actuator, wherein a drive member made up of an SMA is extended between a moving member and wire supporting member via a drive member supporting member, and current is applied to the unnecessary portion of the drive member located between the wire supporting member and drive member supporting member, whereby the unnecessary portion of the drive member is cut off by melting, with the result that the size of the protrusion left behind after cutting of the SMA is reduced, and there is no need of giving consideration to the durability of a cutter otherwise used for cutting purposes.
