1. A thermal diffusion coefficient measuring device to be used in contact with a skin surface of a living body, the thermal diffusion coefficient measuring device comprising:
a biological information sensor which comprises:
a temperature sensor which is provided at a position to contact the skin surface of the living body and which is configured to detect a skin temperature; and
a thin heat flux sensor which is provided at a position to contact the skin surface of the living body while being adjacent to the temperature sensor and which is configured to detect heat flux generated in a normal direction to the skin surface of the living body; and
a heating/cooling control unit which changes heating and cooling the skin surface in a certain period so as to enable measurement, by the biological information sensor, of a thermal diffusion coefficient of a thermal resistance component that is present in a route from the biological information sensor to an internal deep part of the living body,
wherein the heating/cooling control unit is provided so as to be removable from and installable to the biological information sensor,
wherein the thermal diffusion coefficient measuring device further comprises a transmitting unit configured to transmit, as sensed data, the skin temperature detected by the temperature sensor and the heat flux detected by the thin heat flux sensor to the outside, and
wherein the transmitting unit is configured to transmit, at least once, the thermal diffusion coefficient measured by using the heating/cooling control unit before the heating/cooling control unit is removed from the biological information sensor.
