This paper describes a novel method to measure the thermal conductivity of individual carbon nanotubes (CNTs) by using a suspended sample‐attached T‐type nanosensor. The CNTs used were made by an arc‐discharge evaporation method. We could successfully measure the thermal conductivity of individual carbon nanotubes in the range of temperature from 77 K to 320 K, and the results show that the thermal conductivity increases with the temperature and approaches an asymptote near 320 K.
