In this paper we’ve proved that if X is a uniformly smooth Banach space, then the IAP (isometric approximation problem)on the space B(X, l_∞(Γ)) for some infinite index set Γ is aftirmative if and only if dimX=l or ∞. Particularly the IAP on spaces B(l_p, m) and B(L_p[0, 1], m) are affirmative(1<p<∞).
