Zusammenfassung:	PURPOSE:To control adhesive strength in adhering two materials to be adhered, by forming adhesive coating and non-coating parts to the surface to be adhered of at least either one of both materials to be adhered in a predetermined area ratio. CONSTITUTION:Two materials 11, 12 to be adhered are respectively formed from fluororesin films and an adhesive 13 is interposed between both films 11, 12 in a lattice like pattern and said films are adhered only at the parts of the adhesive 13. The hot melt type adhesive 13 is applied to the surface to be adhered of the fluororesin film 11 using a screen printing machine so as to form a coating pattern consisting of lattice like coating parts 21 and non-coating parts 22 other than said parts 21. After printing, the other film is superposed on the film having the adhesive printed thereon by a press machine. By this method, by changing an adhesive coating area, adhesive strength can be controlled.
