A buoy structure includes a buoy body, a transparent shell and a luminous module. The buoy body is a middle cavity body. The buoy body is provided with a threading slot through the cavity body and a joint part arranged at the top. One end of the transparent shell is provided with an assembly part and a holding space is formed, wherein the assembly part is combined with the joint part. The light-emitting module is stored in the holding space. Thus, the fishing line can directly pass through the threading groove, so that the center of gravity of the whole buoy body is closer to the center, so that the fisherman can accurately swing the bait to the preset position.一種浮標結構，包括一浮標本體、一透光外殼及一發光模組。浮標本體為一中空腔體，浮標本體具有貫穿中空腔體的一穿線槽及設置於頂端的一結合部。透光外殼的一端設有一組裝部且形成有一容置空間，其中組裝部結合於結合部上。發光模組收納於容置空間。藉此，魚線能夠直接穿過穿線槽，使浮標本體整體重心較靠近中心，以利釣魚者準確地甩餌至預設位置。
