A spool for a fishing reel attached to a reel body of the fishing reel includes a spool body, a spool ring, a fixing ring and a first regulating part. The spool body has a bobbin trunk, an annular flange extending from the bobbin trunk in a radially outward direction that intersects the spool axis, and a tubular connecting portion extending from the flange. The spool ring surrounds an outer peripheral edge of the flange, and is attached to the flange so as to be separable. The fixing ring is attached to the spool body via the tubular connecting portion so as to be separable and is configured to fix the spool ring against the flange from the front direction. The first regulating part regulates relative movement of the fixing ring with respect to the spool body and is detachably attached to the tubular connecting portion.
