PROBLEM TO BE SOLVED: To provide a technology capable of compensating the measurement temperature difference due to the positional relationship between a heat source and a temperature sensor.SOLUTION: In a ring type heat source measurement device 4, a heat receiving unit 411 comes into contact with a measuring object 7 to receive heat, and heat is transferred through a first heat diffusion body 412, a heat transfer layer 413, a second heat diffusion body 414, and a heat radiation unit 415 in this sequence and is radiated. The temperature of the first heat diffusion body 412 is measured by a first temperature sensor 416, the temperature of the second heat diffusion body 414 is measured by a second temperature sensor 417, and the heat flow is calculated on the basis of these temperatures. Due to the thermal diffusion effect of the first heat diffusion body 412 and second heat diffusion body 414, the temperature measurement can be performed stably and accurately regardless of a relative position between an arterial vessel 8 as a heat source and the first temperature sensor 416 or the second temperature sensor 417.SELECTED DRAWING: Figure 2 |
