PROBLEM TO BE SOLVED: To provide a compressed composite resin foam-molded article, which has excellent flexibility and little permanent set, and weight of which can be reduced.SOLUTION: Provided is a compressed foam-molded article formed by subjecting an in-mold molded article of foamed particles to a compression treatment. The compressed composite resin foam-molded article is composed of a composite resin comprising 5 to 25 wt% of a polyethylene-based resin and 75 to 95 wt% of a polystyrene-based resin (where a total of the two resins is 100 wt%). An insoluble matter mixture of a xylene insoluble matter when the composite resin is subjected to Soxhlet extraction with xylene and an acetone insoluble matter contained in the xylene solution after the Soxhlet extraction shows a degree of swelling of 1.25 or more in methyl ethyl ketone at 23°C. A value obtained by dividing 10% compression stress [kPa] by an apparent density [kg/m] and a compression permanent set are adjusted to 3 or more and 10% or less, respectively, by the compression treatment. |
