ABSTRACT:
There is prepared at least one flame retardant sheet member in which a flame retardant layer comprised of a flame retardant agent having extinguishability is sandwiched between resinous layers. One end face of the at least one sheet member and another end face of the at least one sheet member are opposed to each other while forming a clearance therebetween. A first welding member having a first width larger than a width of the clearance is placed on one face of the sheet member. The first welding member is welded with the end faces of the at least one sheet member such that the first welding member is melted and pushed into the clearance while the flame retardant agent situated in the vicinity of the end faces is pushed out from the clearance, thereby forming a joint portion. A second welding member having a second width larger than the first width is placed on the joint portion. The second welding member is welded with the at least one sheet member.
