An upper bound estimate in the law of the iterated logarithm for Σf(nk ω) where nk+1∫nk≧ 1 + ck-α (α≧0) is investigated. In the case α<1/2, an upper bound had been given by Takahashi [15], and the sharpness of the bound was proved in our previous paper [8]. In this paper it is proved that the upper bound is still valid in case α≧1/2 if some additional condition on {nk} is assumed. As an application, the law of the iterated logarithm is proved when {nk} is the arrangement in increasing order of the set B(τ)={1i1...qτiτ|i1,...,iτ∈N0}, where τ≧ 2, N0=NU{0}, and q1,...,qτ are integers greater than 1 and relatively prime to each others.
