  "textContent": "A modified natural rubber includes a linking structure represented by general formula (C), the linking structure having been formed by allowing polyisoprene, having a structure represented by general formula (A) and/or general formula (B), to bind in the structure to an amino compound having two or more primary amino groups. In the formulae (A) and (B), X represents a hydrogen atom or a methyl group, and Ps represent a polyisoprene unit. In the formula (C), W represents a residue of the amino compound from which amino end groups are removed, and Q represents at least one selected from the group consisting of general formulae (Q-1) to (Q-4), and m represents 2 to 4. In the general formulae (Q-1) to (Q-4), *indicates binding to a carbon atom of a polyisoprene unit, and *indicates binding to a carbon atom of the residue represented by W.",
