= METHOD FOR PRODUCING MOLDED ARTICLE OF THERMOPLASTIC RESIN EXPANDED BEADS =

'''Abstract''':
a method for producing a molded article of thermoplastic resin expanded beads that includes cracking filling and in-mold molding. the expanded beads have a columnar shape and a defective portion that is a through hole and/or a groove. a ratio ca/a of an average cross-sectional area ca per defective portion to an average cross-sectional area a of a cut surface of the expanded bead obtained by cutting the expanded bead at a center in an axial direction along a plane perpendicular to the axial direction is 0.01 or more and 0.20 or less, and a ratio ct/a of a total cross-sectional area ct of the defective portion to the average cross-sectional area a of the expanded bead is 0.02 or more and 0.20 or less. when the mold is completely closed, a filling rate f of the expanded beads is 125% or more and 220% or less.
