Abstract: A necessary and sufficient adhesive force of an adhesive agent layer is certainly kept while the dot diameter of the adhesive agent is made smaller and the thickness of the adhesive agent layer is made smaller. For the purpose, in an adhesive product, comprising an adhesive agent layer in which dots of a dot-form adhesive agent 12 are intermittently arranged, and a base material 11 which supports the adhesive agent layer, the dot diameter of the adhesive agent 12 is made into a very small value of less than 1.5 mm, and the thickness of the adhesive agent layer is set to less than 25 ?m while the area ratio that is the proportion of an area where the adhesive agent 12 occupies per unit area of the base material 11 is set to 0.7 or more.

Abstract: A length composite member comprising a metallic sheet and a rigid synthetic resin coating is bent to be arcuate in transversal section. The thickness of the metallic sheet of such composite member as bent to be arcuate in transversal section is extremely small as compared with the radius of curvature of the desired arcuate sectional curve. A plurality of small arcuate sectional bent portions in transversal section are formed distributed in the transversal or width direction of the metallic sheet. The centers of the respective curvatures of these plurality of small arcuate, sectional bent portions in transversal section are selected to exist on the same side as that of the center of curvature of the composite member bent to be arcuate. The metallic sheet is generally bent in advance to be arcuate in transversal section and both main surfaces of the metallic sheet thus bent are coated with rigid synthetic resin.
