PROBLEM TO BE SOLVED: To provide a glass fiber bundle body which has better tensile strength in comparison with the conventional while having a construction of being coupled without using adhesion agent at a fiber junction part and provide a glass fiber bundle body manufacturing method in which tensile strength improvement is realized while coupling strands without using the adhesion agent.SOLUTION: A glass fiber strand 1 includes a fiber junction part 4 in which a first strand 2 and a second strand 3 each of that is constituted by bundling plural glass fibers are superimposed, and is constituted by coupling the first strand 2 and the second strand 3 to each other at the fiber junction part 4, and the fiber junction part 4 includes plural jointing parts 5, 5, 5 in each of which the first strand 2 and the second strand 3 are jointed to each other.SELECTED DRAWING: Figure 1 |
