A nuclear magnetic resonance (NMR) resonator (1; 31) comprising an inductive section (6) and a capacitive section (6a), wherein the inductive section (6) is band-shaped and surrounds a substantially cylindrical volume under investigation (5), wherein the capacitive section (6a) is formed from one or more discrete capacitor(s) (13; 13a, 13b, 13c, 13d), and wherein the ends (7, 8) of the band-shaped inductive section (6) are connected through one or several capacitor(s) (13; 13a, 13b, 13c, 13d) of the capacitive section (6a), is characterized in that the inductive section (6) is formed from a dielectric flexible foil (2) which is conductively coated on both sides and the ends (7, 8) of the band-shaped inductive section (6) overlap, wherein the outer coating (4) of the inner end (7) is electrically conductingly connected to the inner coating (3) of the outer end (8), with one or more through-connections (10) being provided in the area of the inner end (7) of the band-shaped inductive section (6), and the outer coating (4) being connected in the area of the outer end (8) to the inner coating (3) in the area of the inner end (7) via one or more capacitor(s) (13; 13a, 13b, 13c, 13d) and one or several through-connection(s) (10). The inventive NMR resonator for low-resolution NMR has a simple construction and provides NMR measurements of improved quality at low resonance frequencies.
