In order to enable the measurement of thermal property information about a subject, this thermal diffusion coefficient measuring device, which is used by contacting the surface of a living body, is provided with: a biological information sensor comprising a temperature sensor and a heat flux sensor; and a heating/cooling control means. The temperature sensor is provided at a position contacting the surface of the living body, and operates so as to detect skin temperature. The heat flux sensor is provided at a position contacting the surface of the living body, while being adjacent to the temperature sensor, and operates so as to detect heat flux on the surface of the living body. The heating/cooling control means enables the measurement of the temperature diffusion coefficient of a thermal resistance component that is present between the biological information sensor and a deep inner portion of the living body.

In order to determine information about the generation of heat in a bearing () in a simple manner, a bearing () includes an outer ring () secured to a securing member, and an inner ring () provided on the inside of the outer ring () and secured to a shaft that rotates in the circumferential direction relative to the securing member. A thermal flow sensor () is provided as a coating on a securing-side surface that includes the outer ring (), and generates a thermoelectromotive force including information about frictional heat generated with the rotation of the shaft.
