The utility model discloses a guide wire core wire structure which comprises a core wire body, the core wire body comprises a plurality of wire body units which are connected in sequence, and one endof each wire body unit is provided with a small-diameter section. Compared with the prior art, the core wire is formed by connecting the plurality of wire body units with the machined small-diameter sections, so that the core wire is prevented from being machined while being dragged, torsion generated by machining to the core wire is avoided, and the problem that the core wire is prone to being twisted and wound during core wire machining is solved. 本实用新型公开了一种导丝芯丝结构，包括：芯丝本体，所述芯丝本体包括若干个依次连接的线体单元，每个所述线体单元的一端均设有小径段。本实用新型，相比现有技术，芯丝用多个已经加工有小径段的线体单元连接而成，避免了芯丝在牵引的同时加工，避免了加工对芯丝产生的扭力，解决了芯丝加工时容易引起芯丝线卷扭曲缠绕的问题。
