A two-terminal resistor (2) having a positive temperature coefficient of resistivity, comprised of a plurality of disc-shaped resistive elements (1) which are arranged and held together in a stack, whereby: each resistive element (1) has two oppositely-situated principal surfaces (3), each of which is metallised substantially in its entirety; a metallic arm (7) is situated between each pair of adjacent resistive elements (1), and is soldered to a principal surface (3) of each element (1) in the pair; a metallic arm (7') is soldered to the terminating principal surface (3') at each end of the stack; part of each metallic arm (7, 7') protrudes outward beyond the boundary of the stack; the protruding parts of the metallic arms (7, 7') with an even ordinal (n=2,4,6) are rigidly connected to a first terminal (9a), and the protruding parts of the metallic arms (7, 7') with an odd ordinal (n=1,2,3) are rigidly connected to the second terminal (9b).
