Abstract

A modified conjugated diene-based polymer, satisfying the following <condition (i)> to <condition (vi)>: <condition (i)> a Mooney viscosity measured at 100°C is 100 or more and 180 or less; <condition (ii)> a Mooney stress relaxation measured at 100°C is in a range of 0.10 to 0.40; <condition (iii)> a glass transition temperature is -95°C to -45°C; <condition (iV)> a content of silicon atoms is 100 ppm by mass or more with respect to a total amount of the modified conjugated diene-based polymer; <condition (V)> a content of nitrogen atoms is 50 ppm by mass or more with respect to a total amount of the modified conjugated diene-based polymer; and <condition (Vi)> a content of an antioxidant is 0.5 parts by mass or less with respect to 100 parts by mass of the modified conjugated diene-based polymer.
