1. A fluorescent agent concentration measuring apparatus comprising:

  • an excitation light source to radiate excitation light to a sample containing a body fluid taken from a living body administered with a fluorescent drug, the excitation light allowing the drug to emit fluorescence;

    a fluorescence detection portion to detect the fluorescence;

    a fluorescent agent concentration calculation portion to calculate the concentration of the drug in the living body, based on a detection signal from the fluorescence detection portion; and

    a peak time estimation portion to estimate the peak time after administration of the drug into the living body, when the concentration of the drug in the living body tissue is the highest, based on the elapsed time after administration of the drug to the living body and the calculated concentration of the drug, wherein,in an optical path from the excitation light source to the fluorescence detection portion, one or more optical members and one or more optical filters are disposed, wherein each of the one or more optical members and each of the one or more optical filters have a predetermined refraction index constant in a plane orthogonal to an optical axis of the optical path.
