Abstract
A method of manufacturing a medical linear member includes a step of forming a first spiral body () whose cross-sectional shape is a substantially perfect circular shape by spirally winding a base body () having a plurality of arrayed wires () formed of a shape memory alloy, around a winding core (), a step of performing a first shape memory process on the first spiral body (), a step of cutting the first spiral body () into a first predetermined length, a step of removing the winding core () from the cut first spiral body (), a step of forming a second spiral body () whose cross-sectional shape is a flat shape by compressing the first spiral body () in a diametral direction, and a step of performing a second shape memory process on the second spiral body ().
