PURPOSE: To get rid of fluctuation of a const. loading set ratio and to obtain a laminated body for an interior material without spoiling gas permeability of a skin material by coating one face of an elastic foamed body with a powder adhesive in an irregular arrangement and being uniformly coated per unit area to form an adhesive layer and laminating a skin material with gas permeability on the adhesive layer.
CONSTITUTION: One face of a foamed body 1 is coated with a powder adhesive in an irregular arrangement being approximately uniform per unit area to form an adhesive layer 2, which is then adhered with a gas permeable skin material such as a leather. When the skin material is a leather, as there exists a foamed body as a backing material, a const. loading set ratio becomes uniform and the adhesive layer 2 does not spoil gas permeability of the leather caused by an irregular arrangement of the powder adhesive and occurrence of wrinkles is less. As the foamed body 1, a polyurethane foam with a cell number of 30/25mm width or more is used and the powder adhesive 2A forming the adhesive layer 2 has a particle diameter of 300-500μm. In addition, when the number of the powder adhesive 2A per 1cm2 one face of the foamed body 1 is 16-32, adhesive strength with the skin material 3 is sufficient and feeling is good and there exists no occurrence of wrinkle.
