N2 - Superconductive energy gap of YBa2Cu3O7−δ are measured in anovel broken film edge junction. (001), (103) and (110) oriented films are broken in a cryogenic environment along the appropriate directions together with the SrTiO3 substrate. Pb electrode is brought close in situ to the clean broken film edge. The normalized energy gap 2Δ(0)/kBTc measured in the direction along and perpendicular to the Cu-O plane are found to be 5.9±0.2 and 3.6±0.2 respectively. These values are independent of the variation in the values of Tc within the examined range of 40K∽90K.
