Abstract
In a tubular structure for forming a fishing rod, an amorphous metal long fiber tape is spirally or crosswise wound on a prepreg sheet tube with a predetermined pitch, not being overlapped in each turn, so that the prepreg sheet and the amorphous long fiber tape are joined together with high adherence, whereby its twisting strength, collapsing strength and bending strength are improved.
