A modified conjugated diene-based polymer is produced using production method that includes a step of reacting a conjugated diene-based polymer having an active end with a compound [M]. The conjugated diene-based polymer having an active end is produced by polymerizing a monomer including a conjugated diene compound in the presence of a polymerization initiator including at least one of an alkali metal compound and an alkaline earth metal compound. The compound [M] has a functional group F1, a functional group F2, and a functional group F3 and no active hydrogen. F1 is a functional group such as "*1-C(=E)-O-" (*1 represents a bond to a carbon atom that constitutes a carbon-carbon unsaturated bond in a chain-like structure or ring-like structure, or a bond to a tertiary carbon atom), F2 is a functional group such as "-C(R7)=N-", and F3 is a functional group such as "-Si(R8)2(OR9)".
