PROBLEM TO BE SOLVED: To improve impact resistance, loading resistance and stress crack resistance of a polyethylene blow-molded article in which electrically-conductive materials such as an electrically-conductive carbon black are incorporated, and to hold fluidity and good blow moldabilities while electrical conductivity is exhibited. SOLUTION: In the polyethylene blow-molded article, a core layer is composed of a high-density polyethylene and is at least 50% of the thickness of a cross-section, and as a surface layer or an inner layer, or the surface layer and the inner layer, an electrically-conductive layer incorporating the carbon black as an electrically-conductive filler is provided, and the base resin for the electrically-conductive layer consists of a polyethylene with a melt flow rate of larger than 0.1 g/10 min.
