摘要: A synthetic resin laminate composed of a supporting plate having protrusions and a foamed sheet having fine through-holes and fixed to the protrusions is produced by placing a foamed sheet extruded on the protrusions of a supporting plate heated to a temperature suitable for fusion-fixing and applying a draft to the supporting plate at a speed more than, but not exceeding 5 times the speed of the foamed sheet.
