<P>PROBLEM TO BE SOLVED: To provide an extrusion-foamed non-crosslinked polyethylene article excellent in low temperature extrusion workability, heat resistance, foaming moldability, and surface chracteristics, and having closed cells and a high expansion ratio. Ž<P>SOLUTION: The extrusion-foamed non-crosslinked polyethylene article is produced by molding a polyethylene-based resin composition including 99.9-50 wt.% of an ethylene-based polymer (a) satisfying the following requirements (A)-(C) and 0.1-50 wt.% of a linear low density polyethylene (b) satisfying the requirement (H), wherein, (A) the density is ≥925 and <965, (B) the melt flow rate is 0.1-20, (C) the number of terminal vinyl groups is ≤0.2 per 1,000 carbon atoms, and (H) the density is ≥925 and <965.
