CONSTITUTION:An aggregate of resin particles comprising polypropylene resin particles of a particle diameter of below 5mm. and showing such a behavior that when 20 particles of this resin are placed on a horizontal mirror-finished glass plate and the slope of the glass plate is increased at a rate of 10 deg./min, the resin particles satisfy the relationships: 0 deg.<theta1<5 deg., 0 deg.<theta10<15 deg., and 1<=theta10/ theta1<7, wherein theta1 is an angle of the glass plate with the horizontal at which the first resin particle begins falling, and theta10 is an angle of the glass plate with the horizontal at which the tenth resin particle begins falling. The particle diameter of the polypropylene resin particles need to have an upper limit of 5mm. because when the particle diameter of the foamed particles obtained by pre-expansion of the resin particles is too large, short shot of a mold occurs or preparation of a molding of a complicated shape becomes impossible.
