1. A method for measuring the concentration of a component contained in a bodily fluid comprising the steps of:

  • taking a bodily fluid from a living body;

    separating a sample to be measured from said bodily fluid taken in said bodily fluid taking step;

    measuring the refractive index of said sample separated in said sample separating step; and

    calculating the concentration of substance to be measured contained in said sample to be measured or said bodily fluid based on said refractive index measured in said refractive index measuring step, wherein a porous molecular weight selective film for allowing the substance contained in said bodily fluid to selectively permeate therethrough is used in said sample separating step.
