wherein the polystyrene-based composite resin particles are impregnated with a volatile blowing agent and are pre-expanded to obtain pre-expanded particles;
the obtained pre-expanded particles are immersed in tetrahydrofuran for 24 hours to obtain an extract A; and the pre-expanded particles are divided into two halves through the center to prepare halved particles, and the halved particles are immersed in tetrahydrofuran for 24 hours to obtain an extract B; and
the obtained extract A and extract B are subjected to a GPC (gel permeation chromatography) measurement and obtain the following results:
the polystyrene-based resin having a weight-average molecular weight (Mw) of 100,000 to 500,000 gives a peak obtained from chromatograms for the extract A and for the extract B; and
a ratio Ps : Pi stands at 1 : 10 or higher, in which Ps indicates peak top intensity of the chromatogram for the extract A, and Pi indicates peak top intensity of the chromatogram for the extract B; or
a ratio Ss : Si stands at 1 : 10 or higher, in which Ss indicates a peak area of the chromatogram for the extract A, and Si indicates a peak area of the chromatogram for the extract B.

The non-crosslinked foamed polyethylene resin particles can simply afford an antistatic molded non-crosslinked foamed polyethylene resin body that has a small shrinkage ratio with respect to mold dimension, is deformed in a small degree, and has good surface stretch. Shrinkage ratio = (BD-VBD) x 100/VBD (1) In the formula, BD is a bulk density of the non-crosslinked foamed polyethylene resin particles at 23°C and 0.1 MPa (under standard atmospheric pressure), and VBD is a bulk density of the non-crosslinked foamed polyethylene resin particles at 23°C under a reduced pressure of 0.002 MPa or less.
