SOLUTION: The substantially uncross-linked expanded particles are obtained by carrying out a surface-modifying step of keeping a dispersion formed by dispersing resin particles containing a polypropylene resin as a substrate resin in a dispersion medium in which an organic peroxide is present at a temperature lower than the substrate resin melting point of the polypropylene resin particles and substantially decomposing the organic peroxide, decomposing the organic peroxide and thereby providing substantially uncross-linked surface-modified particles and expanding the resultant surface-modified particles with a blowing agent. The polypropylene resin expanded particles are characterized in that the substrate resin is composed of (1) a copolymer of propylene and an olefin other than the propylene in ≤0.1 wt.% (except 0) ratio of the olefin component other than the propylene in the copolymer or (2) a mixture of propylene homopolymer with the copolymer of the propylene and the olefin other than the propylene in ≤0.1 wt.% (except 0) ratio of the olefin component other than the propylene in the mixture.
