A fishing line guide member is formed in a ring shape, and has a curve surface curved from an inner circumferential side toward an outer circumferential side in a cross-sectional view with respect to a cross-section of the fishing line guide member taken along a cut plane including an axis line of the fishing line guide member. In an inner circumferential side part of the curve surface, R1 is larger than R2, in which R1 denotes a curvature radius of an axial center side part of the curve surface and R2 denotes a curvature radius of an axial end side part of the curve surface.
