PROBLEM TO BE SOLVED: To provide pre-expanded polyolefin-based resin particles which, in spite of using a so-called higher fatty acid/glycerol ester which is safer but is poorer than other surfactants in the capability of giving antistatic performance in a usual humidity atmosphere, can give a polyolefin-based resin in-mold foam capable of stably exhibiting good antistatic performance in an atmosphere of a humidity of about 50% at which the in-mold foam is usually used. SOLUTION: The pre-expanded polyolefin-based resin particles includes a ≥6 and ≤24C fatty acid/glycerol ester and/or a ≥6 and ≤24C fatty acid/polyglycerol ester and a ≥6 and ≤20C aliphatic alcohol.
