Abstract
A manufacturing method for an article having a foamed layer, comprising the steps of: retaining and fixing an adherent portion having a resin-made reinforcing layer and a foamed layer, the reinforcing layer having an integrally formed design surface; and vibration welding, with a low-frequency wave, the reinforcing layer and a base portion together so as to be integrally bonded while the base portion, formed of resin which can be welded to the reinforcing layer, is in contact with the reinforcing layer. Thus, it is possible to reduce the processes which require a great deal of man-hours, such as the applying and drying of an adhesive material, sewing and mechanically affixing. Consequently, an attractive article can be produced while reducing manufacturing man-hours and providing for automated manufacture.
