The penetration of a magnetic field into a finite-width tunnel barrier is considered. It is shown that the magnetization curve differs from that for an infinitely wide barrier (B. D. Josephson, Revs. Mod. Phys. 36, 216, 1964; I. O. Kulik, Zh. Eksp. Teor. Fiz. 51, 1952, 1966 (Sov. Phys. JETP 24, 1307 (1966); I. O. Kulik and I. K. Yanson, The Josephson Effect in Superconducting Tunnel Structures (in Russian), 1970). The mean field strength does not vary continuously in this case but changes by jumps as the individual vortices enter the junction. Expressions are found for the ''supercooling'' and ''superheating'' fields, which restrict the region of existence of weak superconductivity.
