PURPOSE:To obtain the title sheet having both rigidity and cuttability, not requiring the use of two kinds of resin layers and having good application workability, by sealing the reinforcing base formed on a self-adhesive thermosetting resin composition layer with a heat-resistant resin. CONSTITUTION:The title reinforcing adhesive sheet comprises a reinforcing base and a thermosetting resin composition, wherein the reinforcing base (e.g., glass cloth) is made rigid by sealing with a heat-resistant resin (e.g., phenolic resin or melamine resin), and the thermosetting resin composition layer (e.g., a layer of a composition comprising an epoxy resin of a glycidyl ether or glycidyl ester type) has self-adhesiveness. The use of the above sheet makes it possible to dispense with the use of two kinds of resin layers unlike conventional one, to decrease the amount of resin, to thin the resin layer, to prevent the loosening at the edge of the reinforcing base in cutting the adhesive sheet, and to prevent the coating staining resulting from it. |
