Zusammenfassung:	To provide a mower cutting cord that is improved in cutting performance and quietness.SOLUTION: A mower cutting cord 1 includes: a core part 10 extending along an axis line of the mower cutting cord; and lateral parts 20a arranged helically at an outer peripheral surface of the core part. The lateral parts adjacent in an axial direction are separated from each other. The lateral part has a base part BP where a width of the lateral part in a circumferential direction about the axis line decreases as proceeding to the core part at a lateral part cross section that intersects an extension direction of the lateral part.SELECTED DRAWING: Figure 4 【課題】切断性能および静音性能の改善された草刈機用カッティングコードを提供する。【解決手段】草刈機用カッティングコード１は、草刈機用カッティングコードの軸線に沿って延びる芯部１０と、芯部の外周面において螺旋状に配置された側部２０ａと、を備え、軸線方向に隣り合う側部は互いに離間しており、側部の延伸方向に直交する側部横断面において、側部は、軸線を中心とした周方向における側部の幅が、芯部に向かうにつれて小さくなるベース部分ＢＰを有している。【選択図】図４
