Flux creep is theoretically investigated for a model of a sinusoidal washboard potential in superconductors. An apparent pinning potential depth, U 0 * , defined by the relaxation rate of the shielding current density, is found to be significantly smaller than a given pinning potential depth. In particular, U 0 * reduces to zero at zero temperature, while the given pinning potential depth takes a finite value. The effect of the form of the potential barrier on such a significant flux creep at low temperatures is discussed.
