The AC penetration depth, $\lam$, in a Bi-2223
multifilamentary tape wire was estimated from the slope of
minor magnetization curve. It is found that $\lam$ is
comparable to the thickness of the filament and the
hysteresis loss is reduced from the prediction of Kim
model due to the effect of the reversible fluxoid motion
at high temperatures. It is recommended to reduce the
thickness of the filament below 2~$\mu$m for the reduction
of hysteresis loss at 77~K.
