Expanded polyethylene resin particles include an antistatic agent and a base resin. The expanded polyethylene resin particles are obtained by expanding polyethylene resin particles including the antistatic agent and the base resin, the polyethylene resin particles having a storage modulus of elasticity of 900 to 5000 Pa at an angular frequency of 1 rad/sec in dynamic viscoelastic behavior measurement at 190° C. and a storage modulus of elasticity of 100000 Pa or less at an angular frequency of 100 rad/sec in dynamic viscoelastic behavior measurement at 190° C. The expanded polyethylene resin particles have a low temperature side melting peak and a high temperature side melting peak on a differential scanning calorimetry (DSC) curve obtained when a temperature of the expanded polyethylene resin particles is increased from 20° C. to 220° C. at a heating rate of 10° C./min.
