텐션을 가하였을 때에 연결이 해제되지 않고, 수지를 함침시킨 후, 지장 없이 다이스에 통할 수가 있으며, 성형품에서 뛰어난 외관 품질을 얻을 수 있는 유리 섬유사 연결체를 제공한다. 유리 섬유사 연결체(1)는, 유리 섬유사(2, 3)와, 겹쳐진 양 유리 섬유사(2, 3)의 단부에 수지사(4)가 감겨진 결합부(5)를 구비한다. 결합부(5)가 20~40mm의 폭(W)을 구비한다. 각 유리 섬유사(2, 3)의 직경과 결합부(5)에 감겨진 수지사(4)의 두께의 총합으로서의 결합부 직경(R)이 500~5000μm이며, 각 유리 섬유사(2, 3)의 질량이 200~6000tex일 때, 결합부 직경(R)에 대한 유리 섬유사(2, 3)의 질량의 비의 값이 0.32~2.00의 범위에 있다. Provided is a glass-fiber-yarn joined body that is not disjoined when applied with tension, can be allowed to pass through a dice without trouble after impregnation of resin, and makes it possible to obtain excellent appearance quality in a molded product. The glass-fiber-yarn joined body 1 is provided with glass fiber yarns 2, 3, and a connection 5 in which a resin yarn 4 is wound around ends of both of the glass fiber yarns 2, 3, the ends being superimposed with each other. The connection 5 has a width Wof 20 to 40 mm. When a connection diameter R as a total of diameters of the respective glass fiber yarns 2, 3 and the thickness of the resin yarn 4 wound around the connection 5 is 500 to 5000 µm and a mass of each of the glass fiber yarns 2, 3 is 200 to 6000 tex, a value of a ratio of mass of each of the glass fiber yarns 2, 3 relative to the connection diameter R is in the range of 0.32 to 2.00.
