Beschreibung
Zusammenfassung:The present disclosure provides a laminated structure with a through hollow structure having heat insulation, a light weight, durability, and sound absorption performance to reduce wind noise, transmitted noise, and the like. The laminated structure of the present disclosure has a foamed resin layer having continuous pores containing fused resin foam particles, and an air-impermeable outer layer provided on one side of the foamed resin layer, where a part of the foamed resin layer of the laminated structure cut out with a diameter of 41.5 mmϕ has an amount of air permeability of 2.5 cm3/(cm2·s) to 40 cm3/(cm2·s) measured by the Frazier method in which the foamed resin layer is set as an air introduction side.
