A foamed particle, and foamed product obtained from the foamed particle are provided to reduce the frictional sound between the foamed products even without coating a surfactant. A foamed particle comprises a polypropylene resin composition which comprises 50 wt% or more of a polypropylene resin, 0.05-10 wt% of an olefin-based elastomer modified with an organic acid and 0.01-5 wt% of a fatty acid amide, and has a bulk density of 10-450 g/L. Preferably the olefin-based elastomer modified with an organic acid comprises an olefin polymer segment as a main component and a vinyl polymer segment formed from a vinyl-based monomer having an organic acid unit as a side component. |
