We have measured the angular dependence of the voltage-current characteristics in Bi-2223/Ag tape which has a high critical current density, 33 kA/cm2 at 77 K and self-magnetic field. The angular dependence can be attributed to that of the so-called glass-liquid transition field. It will be shown that the critical current density can be described by the statistics model as a function of the magnetic field and its angle.
