PURPOSE:To obtain a corrosion-inhibiting tape prevented from cracking in a low temperature range and improved in drip of resin during heat curing, by impregnating a fibrous base with a composition comprising a thermosetting one-pack epoxy resin composition and an ultraviolet-curable resin and irradiating it with ultraviolet rays. CONSTITUTION:A fibrous base is impregnated with a mixed resin composition (A) flowable at room temperature. At least either of the surfaces of this tape is irradiated with ultraviolet rays to bring this composition to a semisolid state at room temperature,and the tape is rolled up to obtain the purpose corrosion- inhibiting tape. Said composition (A) is one obtained by mixing 100pts.wt. thermosetting one-pack epoxy resin composition having a normally liquid epoxy resin composition and a curing agent as components with 15-70pts.wt. ultraviolet- curable resin composition (b) comprising an acryl oligomer having an acryloyl or methacryloyl group on its terminal or in the side chain, an acrylic monomer and a photopolymerization initiator.
