To provide a multiple coated optical fiber fixing tool in which the ineffective area unused for fitting a multiple coated optical fiber 2 is made smaller and which can be manufactured in a short grinding time and is miniaturized for meeting the requirement of the optical parts industry.

This multiple coated optical fiber fixing tool 10 is constituted so that fibers 2 are fixed by a ferrule 1 having a plurality of through-holes 1b for fixing the fibers 2 in the axial direction. The array of the through-holes 1b on the front end face 1a of the ferrule 1 is made different from the array of the fibers 2 going out of the rear end face 1d to the outside.
