摘要：
[Object] A hollow stranded wire line, for manipulation, having an excellent torque transmittability is provided.
[Solution] A hollow stranded wire line 2 for manipulation is a hollow stranded wire line 2 that is advantageously used as a stranded wire line for manipulation in a medical instrument, and a side wire 4 or a side strand which is an outermost layer has a forming rate that is greater than 100% and not greater than 110%. The side wire 4 or the side strand having been formed has a spiral shape in which a flatness that is an aspect ratio obtained by a major axis being divided by a minor axis is preferably not less than 1.01 and preferably not greater than 1.10.
