Abstract
The present invention provides an ultra-high molecular weight polyethylene fiber having a viscosity-average molecular weight of 10×104 to 1000×104, wherein the ultra-high molecular weight polyethylene fiber has at least three melting peaks in a heating differential scanning calorimetry curve (DSC curve), and in the melting peaks, the difference between (I) a peak temperature of a melting peak appearing between 140° C. or higher and lower than 150° C. and (II) a peak temperature of a melting peak appearing between 150° C. or higher and lower than 158° C. is 10° C. or less.
