1. A body activity measurement device comprising:

  • a light irradiation unit configured to irradiate light of a specified wavelength on a specified measurement site of a body of a subject;

    a light detector configured to detect the intensity of the light exiting from the aforementioned measurement site based on the irradiated light of the light irradiation unit;

    a time sequence data generator that, based on the time sequence changes of the intensity of the exiting light that the light detector detects, generates time sequence data suggesting the changes in amount or changes in concentration of a specified body substance pertaining to the body activity; and

    multiple baseline correction units that correct baselines that mutually differ in relation to the aforementioned time sequence data obtained when the aforementioned subject performs specified assignments, configured such that the aforementioned baseline correction of the time sequence data can be conducted using one or multiple baseline correction units corresponding to the assignment performed by the subject.
