Beschreibung
Zusammenfassung:	A modified conjugated diene-based polymer, including a coupling polymer,wherein a ratio of the coupling polymer, obtained by gel permeation chromatography (GPC), is 30% by mass or more and less than 70% by mass in the entire modified conjugated diene-based polymer, and a modification ratio obtained by adsorption GPC is 30% by mass or more and less than 70% by mass in the entire modified conjugated diene-based polymer,when a peak top molecular weight, obtained by the GPC, of the coupling polymer of the modified conjugated diene-based polymer is represented by Mpand a peak top molecular weight of a non-coupling polymer is represented by Mp, (Mp/Mp) ≥ 3.4, anda shrinking factor (g') is less than 0.60.
