We report the final results of the Milano experiment, carried out in order to measure the electron antineutrino mass from the study of the 187Re beta decay end-point. We used ten microcalorimeters of AgReO4 with a total mass of 2.17 mg and a total activity of 1.17 Hz. We collected 6.2·106 events above 700 eV. The limit on the antineutrino mass achieved is mν < 15 eV. We also give the most precise estimate for the 187Re transition energy and lifetime.
