1. A measurement condition setting fixture for setting measurement conditions, including a positional relationship between a prescribed site of a living body and a measuring optical system at desirable conditions in measurement of living body information, including irradiating the prescribed site with light from the measuring optical system and obtaining living body information based on the light obtained from the prescribed site, the measurement condition setting fixture comprising:

  • a measurement site securing section that can be attached to the prescribed site; and

    at least one measuring optical system securing section, which is adapted for having selectively coupled thereto a part of the measuring optical system, for securing the part of the measuring optical system and the prescribed site in a prescribed positional relationship when the part of the measuring optical system is coupled to the measuring optical system securing section, wherein the part of the measuring optical system is coupled to the at least one measuring optical system securing section at the time of measurement thereby realizing the desirable measurement conditions, and the part of the measuring optical system is detached from the measuring optical system securing section when no measurement is performed, and wherein the positional relationship between the prescribed site of the living body and the measuring optical system does not change when the part of the measuring optical system is attached, detached and then reattached to the at least one measuring optical system securing section.
