<P>PROBLEM TO BE SOLVED: To provide a carbon fiber-wound tape having improved workability and produced by winding a carbon tape on a cylindrical core material, and to provide a production method therefor. <P>SOLUTION: The carbon fiber-wound tape produced by winding a carbon fiber tape comprising a composite material comprising carbon fibers and an olefinic resin on a cylindrical core material is characterized in that the carbon fiber tape width (W) determined by formula (I) is in a range of 5 to 100 mm; the minimal diameter (D) of the cylindrical core material wound with the carbon fiber tape having the width (W) in the range of 5 to 100 mm is determined from formula (II): 0.2×10<SP POS="POST">-3</SP>×N≤W≤2.0×10<SP POS="POST">-3</SP>×N (I), (wherein, N is the number of the carbon fibers constituting the carbon fiber tape, capable of giving the width (W) in the range of 5 to 100 mm); and 4.5×F×t≤D (II) (wherein, F is the amount of the carbon fibers in a range of 20 to 60 mass%; t is the thickness of the carbon fiber tape in a range of 0.1 to 1.0 mm). <P>COPYRIGHT: (C)2012,JPO&INPIT |
