1. A blood sugar level measuring apparatus comprising:

  • a heat amount measuring portion for measuring a temperature deriving from a body surface in order to obtain information used for the calculation of the amount of heat transfer due to convection and the amount of heat transfer due to radiation, which are related to the dissipation of heat from said body surface;

    an optical measuring portion for irradiating said body surface with light in order to obtain measurement values related to the blood hemoglobin concentration and the hemoglobin oxygen saturation inside tissue;

    a memory portion for storing a measurement value relating to the blood hemoglobin concentration measured using a blood sample that is separately collected, and for storing relationships between parameters corresponding to said temperature, said blood hemoglobin concentration and said hemoglobin oxygen saturation inside tissue, the volume of blood flow inside tissue, and blood sugar levels;

    a calculation portion for converting a plurality of measurement values inputted from said heat amount measuring portion and said optical measuring portion, into said parameters individually, and for calculating a blood sugar level by applying said parameters to said relationships stored in said memory portion; and

    a display portion for displaying the result of calculation in said calculation portion, wherein the parameter corresponding to said blood flow volume inside tissue is generated on the basis of a ratio between the blood hemoglobin concentration inside tissue and the blood hemoglobin concentration measured using said blood sample.
