PROBLEM TO BE SOLVED: To provide a production method of a skin material coating foam particle molding, capable of preferably fusing polypropylene-based resin foam particles in a hollow molding, without using special-shaped foam particles.SOLUTION: Foam particles are formed of a polypropylene-based resin having a melting point in a specific range, the polypropylene-based resin forming the foam particles comprises a crystal structure comprising a melting peak (unique peak) being unique to the polypropylene-based resin, and one or more melting peaks (high temperature peak) on a higher temperature side relative to the unique peak, in a DSC curve, and in the DSC curve, a total melting heat quantity exceeds 75 J/g, and a ratio of the melting heat quantity of the high temperature peak relative to the total melting heat quantity is in a specific range, and a melting heat quantity on a part equal to or more than top temperature of the high temperature peak is in a specific range.SELECTED DRAWING: None |
