A stitched laminate, in which plural sheets respectively having plural tow-like carbon fibers arranged in parallel to each other are laminated, with the orienting directions of the carbon fiber yarns of the respective sheets kept at different angles against a reference direction, and are stitched integrally using stitching threads. The fineness of each of the carbon fiber yarns is in a range of 1,200 to 17,000 Tex, and the pitch of the arranged carbon fiber yarns is in a range of 8 to 60 mm. In the sheets, the arranged carbon fiber yarns are widened in yarn width to ensure that no gap substantially exists between the respectively adjacent carbon fiber yarns. The plural carbon fiber yarns supplied to form sheets are respectively brought into contact with plural rollers, to be bent and widened in yarn width. <IMAGE> |
