The object of the invention is a thermometer based on CB tunnelling, which comprises a sensor component and devices for measuring its voltage-current dependence. The sensor includes a chain of several, at least ten, nanoscale tunnel junctions (10, 1011) and connection electrodes (2, 3, 31, 311) for connecting the measurement devices to the ends of the chain. The temperature is determined in a manner that is, as such, known, on the basis of the characteristic quantities of the descriptor G/G T of the voltage-current dependence. The measurement array of the sensor (4, 4', 4") includes several tunnel junction chains (4.1 ... 4.10) connected in parallel, for decreasing the total impedance of the array.
