Provided is a steel cord for reinforcing rubber articles which has both rubber penetration and productivity and which allows to reduce the weight of a tire without compromising the strength of the tire when applied to a tire, and a pneumatic tire using the same. The steel cord for reinforcing rubber articles of the present invention is a steel cord for reinforcing rubber articles comprising a core formed by arranging two core filaments in parallel without twisting the filaments together, and six sheath filaments twisted around the core. Letting the diameter of the core filament dc (mm), the diameter of the sheath filament ds (mm) and sheath filament twist pitch p (mm), an average sheath filament interval D represented by the following Formula (I): D=[L−6ds{1+(L/p)2}1/2]/6  (I), (where L=(π+2)dc+πds) is from 25 to 80 μm.
