The invention relates to a thermistor, primarily intended for temperature measurement. The thermistor comprises at least two thermistor plates (14-17) on a carrier (10), adjacent to each other and connected in series. The plates are separated from each other by a preferably elongated gap (18) and the upper surfaces of said plates are largely covered by upper electrode surfaces (24-26). The thermistor plates (14-17) are arranged within a limited area of the carrier (10) so that the maximum aggregate area of the thermistor plates (14-17) is constant, whereas the size of each individual thermistor surface is variable by displacement of the position of the gap(s) (18) within the said limited area of the carrier (10), for adjustment of the total resistance of the thermistor to different values. The invention also relates to a procedure for manufacturing a thermistor.
